Knocked this up on thursday night. Only a few hours work in it and I'm pretty happy with it. I've been wanting to make this variation for a while. Not sure if it's been done before though.

The stickers are vinyl film.

Where does the name come from Wayne? Also, I was wondering how big your 2x2x3 cube is? (the one on the front page)

The 2x2x3 that the Puzzlemeister1 auctioned off was much larger than normal sized cubes. It was made based off of a 4x4x4 mechanism with larger custom made sized cubies.

On the front page near the pictures there are links to some interviews. one of them is all about using 3x3x3s to extend to dominos, 2x2x3s etc. it seems that you put really big 'cubes' around the existing ones, and i was just wondering if this is how wayne made his 2x2x3... the reason i asked is because i know 'looks can be deceiving'. the pic actually looks like theyre 2x2x2 cubies...

wayne are you out there? how big is it??

Mondrian was an artist (early 20th century I think - can't remember). His art was all about 2d geographical shapes, mainly lines of squares, using nothing but primary colours and neutrals. I really liked his art during highschool.

You can see examples of his art here: http://images.google.com/images?q=mondrian&hl=en

Oh the 2x2x3 cubies are from a standard 3x3x3 so they're the same size. The kernal is a keychain cube. Perfect dimensions.

My internet was down yesterday so I couldn't get to the board. I'm here. Standard 3x3x3 cubes attached to a keychain sized 3x3x3 kernal.

??? Just your standard Rubik's cube size. Nothing special. For sticker variations, size doesn'r matter that much.

Sorry Wayne, I meant what size was the mini cube you used in the 2x2x3? There are heaps of different sizes for them and I was wondering what size you used, and if the size does indeed matter.

I dont know about wayne's personally, but it can be made with a keychain inner cube (3x3) and a 57 mm outer cube... I am getting one in a trade. ill give you the size when i get it, but it should be 57 x 38 x 38 mm

tony fisher molded larger cubes around 57mm kernels i think, but you CAN make it with a mini and regular cube

Also, Wayne, did you also have to shave down some of the edges and corners to make it work, or was the keychain cube small enough compared to the regular cube to not have to do that?

I can answer these questions generically, these answers are correct (they may not pertain to wayne)

1. 31mm mini cube (sold @ rubiks.com)
2. The incisions made on the cube, in fisher's diagram on that article on twisty ARE the shaved edges + corners. these can be done with a dremel tool (Ton has done this) or other ways

But, do the edges and corners NEED to be trimmed? If the kernal cube is small enough compared to the final cubie size, no trimming would be neccessary. What I'm getting at is "How small does the kernal 3x3x3 cube have to be to eliminate all trimming to make a regular size (34x34x57mm) 2x2x3 cube?"

Indeed, I've always thought Rubik's cubes had a Mondrian-ish look to them. Apart from that day-glo orange side!

it looks awesome!!! and it wouldnt be too big... so a mini cube and standard 3x3x3 sizes work nicely? what are the dimensions of the cubes you used?

i guess using the same idea, you could make a working 5x3x3??

if you used a micro cube (20mm)
probably no trimming would be needed of the kernel.
but then you get into trimming the outer cube.

if you open a 57mm, the part of it's edge that connects to the mechanism (called "cube connector" here on) is the same size as a 31mm cubie.
now, this part gets cut down and glued to a 31mm to make a 2x2x3.
but, with a 20mm kernel, that cubie connector would have to be trimmed down by 2.3333 mm on each side of it. this is very hard to do.
anything else?

Yes, definately had to shave corners as per the article. 10 Edges completely shaved, 2 edges one half side shaved, 8 Corners half side shaved.

Gives the outer "normal sized" cubies a track to run through.

Restickering my first one. Considering trading it.

All corners MUST be trimmed to give the outer cubies a track. I put the shaved pieces together incorrectly when I first finished the kernel and the puzzle locked.

Minicubes: Don't go any smaller than this as the puzzle will be too weak (a large cubie attached to a very small point).
