Now, after the Cube, I still don't have any plans to make anything like it.
I did not plan to make the Cube.
The problems of puzzles are very near the problems of life.
I'm glad the Cube is reaching new generations, who face it with fresh wonder, curiosity and enthusiasm.
In my teaching, I enjoyed creating models to clearly communicate my thoughts.
A good puzzle, it's a fair thing. Nobody is lying. It's very clear, and the problem depends just on you.
