Incredible! Can you post some pictures of it scrambled?

That is an awesome Square-1 transformation. It must have been a huge amount of work.

That's amazing! An absolute work of art! I'd be interested in knowing how long that took you to complete from beginning to end. Excellent work.

Anthony, it's beautiful! I would love to see it scrambled as well.

Uh... wow. :shock: A very impressive piece of work there, Anthony. I don't know how you keep doing it. I'm kind of scared to ask for scrambled pictures... that looks intimidating enough when it's solved. :wink: Are there still places around to get Square-1 puzzles commercially? I've got a couple of ideas in mind for mods myself, and they don't appear to be sold locally any more. L8r.

I am speechless. Well done. Do you have any internal pictures or individual piece pictures you could share?

Awesome Square-1 shape mod. I don't think I'd enjoy turning it though. I grouse about even the way a Fisher Cube's shape makes it hard to manipulate. This one would drive me insane.

Very nice indeed! I had an idea similar to this earlier in the year. Never got around to it obviously. However, I did manage to start a spherical square one that should be done soon. I hope so at least! Anyway, congrats Anthony!!

Unbelievable, Tony!
This one is beyond any imagination.
How did you even come up with such beauty?
The implementation must have been the hardest, comparing to any other puzzles you've made?
Mind you, having your experience, it might be getting easier making very difficult mods!?
Well done! That was a big surprise!

Nice one Anthony. Am I right in thinking that in it's solved state the Square One is part way through a turn?

Awesome!!!!!!! Very cool!!!!! So do you have any scrambled picture? Like what Aleksey said. So is this your second mold of the square-1 that is different shape other then a cube? What other shape molds do you have in store for use? :wink:

I think we have 2 kings of the puzzle building!
One of my work colleagues, who's surname is also Greenhill is very proud of his last name now.
He certainly recons that this creativity flows in his veins too! :roll:

Wow, what a gorgous mod! It looks like a pain to turn though. I bet this guy can get some pretty funky shapes. I too would like to see some scrambled images
Way to go Anthony!

Thanks to all of you for your comments regarding Greenhill’s Tetrahedron.
Now to answer your questions.

Scrambled pics –
To follow shortly, this week hopefully.
No it is not April 1st, this puzzle does exist. (I take this as a compliment).

Time –
It took just over a month with fairly constant working. This was working on it about 1 to 2 hours a night during the week with maybe 4 hours over the weekends. Very approx. 70 hours. Of course this involved all the working out of the angles and the transformation of the pieces, and, making the templates for the stickers. As this is now all done, the time would be reduced.

Where to get Square 1’s –
Don’t know at the moment.

Internal Pics –
Sorry there are no internal pics. The mechanism is the Square 1, it’s just the pieces have been transformed.

Half turn of Square 1 –
Not to bore you all with ALL my thoughts, ideas, proposals and decisions/scrapped decisions etc. over months and months, this one has been on and off for a long time, more than a year, this would be a long posting if I went into depth. I finally decided on a half turn and a somewhat complicated truncation of the original puzzle. I did not want the middle layer to be continuous on the finished item. The idea of the middle ‘half’ layer on the white face beginning at the bottom corner and rising at a slight angle really appealed to me. I will say that the final result/appearance was not random.

Square 1 transformations –
I have made –
Star Prism, 2 and 3 layer versions (neither of these were my idea)
Dodecagonal Prism
2 Layer Square 1
Greenhill’s Dodecahedron
Greenhill’s 1
Greenhill’s 5 Layer Square 1
Greenhill’s Tetrahedron
Also the copy version I did of the Russian puzzle OLIDJUS, I used a Sqaure 1 to transform.

Hope this answers your questions. If you have any more, please post them.

As I said above, ‘scrambled pics’ to follow.

Anthony

That's what it was meant to be. It was just very similar to the Gigaminx thread ;-). I know you've built awesome puzzles in the past so I didn't really have doubts.

How much do you want for one of these puzzles?
I'd love to have one. I also think there could be a market for the more bizarre and interesting puzzles. Sort of a made to order site. That way there wouldn't be upfront manufacturing costs but they would still be available.

Congratulations on the Tetrahedron btw.

Greetings Anthony,

Incredible puzzle. I was thinking that when first mixing it I would want to write down exactly what I did, but how in the world would I notate the moves?

Just rotate slow and clearly under a video camera?

OH MY!!! I am literallly laughing out loud at the sheer outrageousness of this puzzle! Just when I thought I was tired of the puzzle scene, Anthony knocks our socks off with this little dynamo. Wow! Thanks for making my day.

The edge length is 135mm.
This is 5mm longer than the edge length of the 3x3x3 Tetrahedron that I make.
Both dimensions result from the way the puzzles are transformed, projected out, into the Tetrahedron shape from the 'truncated core'.

Believe it or not I started a Tetrahedron Square-1 and have it half truncated but had to put it aside to make Evil Twins for people with my building time.

I thought of the half twist after I had already truncated the corners and was amazed to see Anthony's creation.

The mechanisim of the Square-1 is pretty shallow under the surface of the puzzle which reallty limits the amount you can truncate which is why Greenhill's Tetrahedron is big.

Once again, very nice Anthony.

There are only two 'face' truncations on this puzzle where it is getting close to the inner mechanism so care has to be taken with the pieces involved until they are complete. When complete (extended etc.) they are okay and do not effect playing with the puzzle in any way, it can be handled/used in exactly the same way as the original. I know it sounds a little odd truncating a face so much then extending the pieces, but believe me it was necessary. It was not just a simple matter of truncating the eight corners for instance. There are a number of edge, face and corner truncations necessary to achieve what I was after.
The overall size was determined, dictated by the projecting out from the truncated core into the Tetrahedron shape.
The dimension given in the previous posting may sound big but when you use the puzzle it is actually very user friendly and you do not notice it, like you would on a 135mm cube for instance. Must have something to do with the the 'tapering' shape. Believe me I have been turning it enough lately.

That is too beautiful.

I just found this site and am amazed with all of the modifications that can be done. I would have to say that this one though is my favorite so far. That has to be fun to play with.
