Updated!

All the pieces have now been made. and I have attached them to the center pieces. sitting there while waiting for another piece to set I couldnt help sit and play with I already got. and it got more and more amusing

Now I got the whole puzzle put together and I really like how it moves and over all looks! I am concidering painting it white after filling out those air holes I unfortunatly got.

now I am off to the sign shop for more vinyl. boy I am gonna get practiced my sticker cutting 4 x 18 stickers

Let me introduce to you,

well I havent settled for a final name yet, for now I will call it "Sigurd's Crystallicube"

It is a 18-sided Cube.
Using a 4x4x4 mechanism. All edges and cornes are trimmed to a minimum. then all center pieces are reshaped.

the result will be 2x2x2 deep cut with 6 face slices that rotates one face or 12 stickers (4 main face sticker pluse the colors of the edges of the pieces.

The idea for this puzzle came from my love of solving the centers of the 4x4x4 cube. then why not make and Only Centers cube I thought.

I have seen a 4x4x4 in this shape before, but not in a centers only version.

I cant wait to play with this one once its done!


plus,
I plan on selling these in near futur if the is enough interest. so let me know!

Greetings,

Sigurd W

These are newest pictures I have taken.
I hope you like them! IMO the plastic color is bad and I wanna dye it sometime, but for now I just wanna finish it.

The mold came out really nice! I actually didnt quite believe it, but you get an exact copy of the masterpiece! wow! (hehe this is quite obvious, but I first realized how it worked as when I actually made it (following instructions )

now, remember I have changed the design of my puzzle so you wont find pictures of a copy of the originally discussed puzzle.

the picture:

Wow that is a pretty awesome puzzle!

Very nice. Some pictures of what you have now would be helpful (i don't really understand the picture, but thats just me)

Looks a lot like LaurentB's Rhombic Dodecaedre.

oh damn! its the same thing! aww man! I thought I really created something special..

well I still think I did.. it just wasnt original

-thanks for letting me know Thomas

but omg reading about how it was discussed and all just takes away my urge for building this.

I still might one day tho because I really would like to play with it. poeple are mentioning how "hard" this would be to solve.
I dont think it would be alot harder than the regular centers of a 4x4x4.

Please don't let that discourage you. I haven't seen this puzzle anywhere but in Laurent's collection. So it might well be that yours, should you make it for real, is going to be the second in the world.

This would be kind of similar to a 4x4 Rhombic Dodecahedron, wouldn't it?

Just the centers of a 4x4 Rhombic Dodecahedron.

wow. I just realized how simple his creation is compared to mine.
but there are two factors of stability that would be my version differ. -not in looks but in mech and feel.

His puzzle uses the 2x2x4 technique (simply adding pieces on the faces of a 2x2x2 puzzle. wich has its stability lying in the internal mechanism.

mine has pieces (edges and corners) that are not visible. wich doesnt support its stability. however using the existing pieces (centers) for the puzzle, I presume will kill the wobbly feel of his idea.

Well... I actually think your solution, using a 4x4x4, is much better. I've always thought LaurentB's Rhombic Dodecaedre and his Lolo's Ocateder are amazing. And I wanted to build them as well. But I never even dared to build a 2x2x4, let alone extending a 2x2x2 on all sides.

When I now read all the old posts, I see that other people already proposed using a 4x4x4, but somehow I never picked up on that. Maybe I should now try to build one. Although I'm not trying to beat you to it!

Thanks for bringing this puzzle to my attention again!

Thomas

People always seem to make puzzle building a competition. Bah! It should be a celebration of creativity and love for puzzles. Who cares who makes it first. It can still be impressive second, third, or even 57th.

I'd love to see one from both of you!

Thomas,
We can build one each and compare them when they are finished if you like
how long time would you need to build it? (I bet you have tons of other ideas, but so do I..)

Noah,
I dont see building as a sompetition at all! I just used to think of this puzzle as my "master piece"! Stupid I was believeing such a 'perfect' puzzle hadnt been build before.

then comes the creater/builder "rights" of copy/ untold rules of puzzle building,

I have to ask LaurentB before attepting anything

It has been a few days, and I'm curious if you have started to build this puzzle or not. I'm very anxious to see more.

you are? well I gotta be honest, it have moved a little down my priority order atm. but that doesnt mean I wont build it.
it just gonna take some time. at least some time before I can somehow see a shape coming. remember I have to custom build 24 custom pieces besides the trimming part.

If you did the mathematics, couldn't you make a master piece, and then mold it? Seems easier than doing them all by hand from scratch.

ok I decided to make the puzzle in a varitation.
I'll make it a truncated rhombic dodecahedron shape instead

so, a 18 sided (6 main faces with additional face on each edge) Cube.

plus, it will make it easier to make (At least much less material to use)

Noah, Yes I surdently could! and I have actually bought all I need for it (Silicone for molds and Resin + Black tone)

Truncate it so the remaining faces of the Rhombic Dodecahedrons are hexagons. That would look mighty interesting.

I have handmade a master piece already I just need to wait for the miliput to harden, so I'll finish it tomorrow.

I cant wait to see how all this molding is gonna come out!

the main faces will be square but the edge faces will be 6 sided

indeed your idea would be interesting but its a whole new puzzle!

WOW! Mod please help me out! can someone please delete those doubles?

you can do it yourself with the little X's next to "edit" and "quote"

I have a question: Are you sure you're right this time?

You can only delete a post if it is the last post in the thread. Sorry for taking that spot with this response

Great puzzle. Except for the fact that you can sticker the edges, I guess, functionally it is the same as Baby Faceright?

yes same mechanism. and same pieces except mine are raised in a manner so it has a face color on each edge as you mentioned. this makes the solution much more interesting.
did you read the whole discussion? its actually a truncation of my original idea

I hadnt heard about babyface before. it would be nice if the database was updated with every new/ old puzzle there is.
it was a nice mod indeed!

I have been thinking of the possability of truncating to a flat surface ( wich would make a 4x4x4 centers only cube, to be exact or Babyface)
and doing the exact same with a 5x5x5 cube and get a 3x3x3 looking result. just like Seneegee says in the thread hehe

I thought that doing that to make a 3x3x3 where both the sides and layers could turn independently would be tight....I never knew it had been done to a 2x2x2 yet.

I was having a hard time getting to sleep last night and my mind was wandering...

Is it possible to make a of spherical version of this puzzle?

I believe it is possible! it would be really cool! great idea!
for now I have some ideas for some (not this one tho) cylinders, but the precise sanding it needs keeps me away abit.

sanding a puzzle into a sphere I can only imagine how hard

Here's the shape I was thinking of, were it's truncated, yet not as far as you did.

http://upload.wikimedia.org/wikipedia/e ... edron2.png

Each of the original faces is a regular Hexagon.

hmm.. what I pictured in my mind was nothing like that picture lol
would you mind drawing lines of the cuts as well?

I believe MANY versions of a larger-cubes-centers-only are possible

Gladly.



It would be interesting to take this a step further, and extend the tips like a 2x2x4, and have those complete the Rhombic Dodecahedron, ergo, the whole puzzle would be like a 2x2x6, but extended on all sides.

I don't see why it wouldn't work.

know what? taking it to the next step as you said (2x2x4 ADD to this) would be CRAZY! I have actually been thinking about how this could be done the last couple of days.
I gotta make a 2x2x4 before going any further with it!! wow

and LOL I couldnt see how it would work (the picture without lines) but its the exact same as mine! was it this you were thinking about from the start (the truncation?

I am not kidding. the idea you mentioned about extending into 2x2x6 in each dimension have been on my mind from the first day I finished the puzzle.

but when I read you saying it, I realized how crazy it would be!

Technically you already did the "2x2x4 add to 6 faces" thing. That's what you can consider the centers of a super cube 4x4 (so permutation is required)


So the idea I had when you originally said you were going to make a different shape, that's the one I had in mind.


After sketching it out, I though about adding back on the part you truncated as a turnable extra layer.

So if you were to add 2 functional layers to each face of a 2x2, and build it into a Rhombic Dodecahedron, that's the idea.

Now normally a 2x2x6 on all faces isn't possible because of when you turn it, the pieces would fall out, but because of the shape of the Rhombic Dodecahedron, I believe the pieces would remain ok.

really? you cant do the 2x2x6 on all sides? weird. thats shape doesnt appeal much anyway IMO

then why do you think the rhombic dodecahedron shape would support? I dont follow you..

It follows the same idea as a cubic 7x7x7. What is holding those piece in? Unless you make it so the foot of the outer most cubies is touching the inner 2x2x2, the piece would fall out.

See the method for making a 2x2x4 here.

http://www.speedcubing.com/ton/2x2x4.htm

If you were to make a 2x2x6, even on just two sides, then do a turn along a 2x6 face, the outer most pieces would fall out, because they are only being held in by the 2x4 pieces. Since those are fully exposed on the side that would be holding in the 2x6 pieces, they would fall out, but not the 2x4s, because the 2x2 pieces are holding those in.


A Rhombic Dodecahedron would retain the surface area required to keep the piece in throughout the turn.

I see! thank you Noah! that cleared things up for me!
I think I mixed the ideas in my head and got confusd. I am still new to this and lots of ideas and mechanisms have yet to be logical to me

hmm, that puzzle would really be awesome!

btw. by cubic 7x7x7 do you mean like 5x5x5 expand idea (olympicube etc)? lol

It can be done. It has been done: twistypuzzles.com/forum/viewtopic.php?t=2341

Sweet modder of God!

Thomas

I'm somewhat talking about Olympicubes.

If you look, the 5x5 and 6x6 cubes are perfectly square, yet the 7x7 has a bloated like curve to it. It's like that because, at 45 degrees, the corner pieces would fall out because there would be nothing supporting it.

So a curve was added to add the necessary support for the outer pieces.

I was taking the same concept with the puzzle idea we were discussing.

Here's a different way of reasoning the 7x7x7 pillow design.
When you twist a slice it makes a circle, and we want the biggest possible circle. A lot of circles stacked on top of one another make a cylinder. The corner piece has to travel in 3 of these cylinders (one along each axis), so take the common area of all 3 (boolean intersection).
If you position that shape at the center of an NxNxN cube, it has to touch every visible cubie for it to work.
The 7x7x7 isn't pillowed out, the corners are being sucked in so they can touch this shape.

If you use this general principle with a 2x2x6, you get 2 BIG cylinders intersected with one small cylinder, and there's no problem whatsoever getting all the visible pieces to touch this shape.

my friend and I had this little discussion on the 5x5x5+ cubes
he said that he had figurd out a way to expand the idea from the middle row and out. simply chucking pieces in between the middle edge and the outer edge. for this to be possible, as you said the corner pieces had to be extended further towards the center to hold on, but thats the only problem as it seems

well I could see a solution in the core size maybe.

I am surprised this hasn't been mentioned:

Looking good W.

Posted: Fri Nov 23, 2007

this has already been made by Mike Grimsley (skeneegee) as seen here

viewtopic.php?t=5098&highlight=

yes Adam the Babyface uses the same idea. buts its not the same puzzle.

People should really skim/read the whole thread. That's the third time it has been mentioned that the puzzle is like Babyface.
