I've always been passionate about geometry and the study of three-dimensional forms.

I'm glad the Cube is reaching new generations, who face it with fresh wonder, curiosity and enthusiasm.

I was somewhat out of place among my classmates; I could not be as bohemian as they were.

Once I completed the Cube and demonstrated it to my students, I realized it was nearly impossible to put down.

A good puzzle, it's a fair thing. Nobody is lying. It's very clear, and the problem depends just on you.

Like after a nice walk when you have seen many lovely sights you decide to go home, after a while I decided it was time to go home, let us put the cubes back in order. And it was at that moment that I came face to face with the Big Challenge: What is the way home?

Our whole life is solving puzzles.
