The above is currently the only image for this item.
The most basic corner-turning hexahedron. This version only has two colours.
There were four different versions of this puzzle produced in the nineties:
Version with 2 colors, 4 colors, 6 colors and the dinosaur version. All four can be found in this museum.
An idea so simple that one might wonder why it was not produced earlier thatn 1995. The first samples of the Dino Cube were designed and made out of paper independently by Robert Webb from Australia in 1985 (please refer to the independent entry) and Stephen Harvey from New Zealand in 1990.
In 1995 mass production of this puzzle (the version with the dinosaurs) started. Liang-Yen Wu convinced S.Y. Liou to also produce the versions with 2, 4 and 6 colors.
Wu distributed the puzzles and initially called the puzzles "Corner-turning Cubes".
It shall be noted that in 1998 James R Holloway applied for a patent which was granted in 2000 under the number given above but that was after the puzzle has already seen the light of day.
This is the two volor version: Two faces are solid yellow, two faces solid white. The other two faces are two-coloured, as seen in the picture.
Edge length: 59 mm
