Congratulations, to Glen Heller, on his creation of the first 5x3x3 that i know of to work. Here are soem of his pics that im hosting temporarily. He has allowed me to reproduce these pictures. I am trying to find out his mechanism, i will post when i have more info. TON, how is your 5x3x3 coming along? Done yet?

My 3x3x5 Concept works! I am know busy to think about the best way to build the pieces. I will finish my 3x3x5 very soon (within 14 days). But I want it to be perfect so I constant rebuild the pieces.

For now for my method you would need:

Four 3x3x3 cubes
Two Square 1 cubes
Sand paper
Dremel Grind stone

I used already $60 on material. I use a solder iron to fuse an fill caps so building is very cheap.

Is it a working 3x3x3 with working 3x3x1 extentions? It is not show scrambled enogh to be sure. From the pictures it could also be a cube which is always confined to a 5x3x3s starting shape, which is a great deal less complex of a puzzle (although still quite impressive to make) then a 5x3x3 whic moves as a 3x3x3 with moveing extentions.

i wish i knew, i asked Glen for more pics, he hasnt responded yet

Glen wont release his mechanism, sorry
