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

I want to try to keep my life the same.

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.

I did not plan to make the Cube.

The problems of puzzles are very near the problems of life.

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?

The Cube is an imitation of life itself - or even an improvement on life.

I do not truly consider myself an icon, but the Cube has been quite successful.

Now, after the Cube, I still don't have any plans to make anything like it.

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

If you are curious, you'll find the puzzles around you. If you are determined, you will solve them.

In my teaching, I enjoyed creating models to clearly communicate my thoughts.
