I did not plan to make the Cube.
A good puzzle, it's a fair thing. Nobody is lying. It's very clear, and the problem depends just on you.
The Cube can seem alive as it heats up in your hand. The fact that each face of the Cube is made of three layers of three blocks has an important meaning.
The problems of puzzles are very near the problems of life.
In my teaching, I enjoyed creating models to clearly communicate my thoughts.
I do not truly consider myself an icon, but the Cube has been quite successful.
