I have been trying to make something in between 2 & 3 dimensions.
It requires mathematical rules.
Alphabet in Cube
42 x 42 x 42 mm , 35 x 42 x 42 mm (26 pieces from "A" to "Z" )
There are 26 cubes.
Each cube is supposed to be divided into 2 parts.
Each part consists of the same alphabet , which is cut in the opposite way : One is as if pulled up at the center of the letter so as to become a pyramid. Another is as if pushed down.
You can not make out what it is,when you look from the side.
You can find an alphabet when you look from above.
