4x4x4 Eastsheen Cube

6.5 x 6.5 x 8.8 cm / 2.6 x 2.6 x 3.5 inch

In 1995 I finished making my original rather poor quality (large) 3x3x4. Because it is one of my favourite puzzles I always wanted to come back to the idea at a later date and make a good quality version. With the release of the Eastsheen cubes this was finally possible and in 2003 I made what I consider to be one of my best puzzles. It was transformed entirely by hand using high impact polystyrene plastic sheet. Standard Rubik's Cube style stickers were used.  
The puzzle can't change shape since it doesn't obey the cuboid shape changing rule-
"A cuboid is capable of shape changing when ( two or more edge unit lengths are different and odd ) or ( two or more edge unit lengths are different and even ) excluding cuboids with a side of one."
In total I have made twelve fully functional cuboids. They are-
2x2x3 (micro), 2x2x4, 2x2x6, 2x2x7, 2x3x4, 3x3x4 (large), 3x3x4 (medium), 3x3x5, 3x4x4, 4x4x5, 4x4x6, 5x5x6.
