He was at Powells technical books tonight. I got my question answered after the question, and answer session was over :-). For those who care it was about whether his twister theory used ordinary complex numbers or higher order ones such as quaternions. He is a neat guy, and I felt smart for understanding the little bits that I did. He is so far beyond me that I feel like I would need a few degrees to even have much of a conversation with him. I think I actually got more than five minutes of his time to myself. I got the impression that because of his standing people ask him very challenging questions on a regular basis, and that because of this he has a constant source of inspiration.

I'm officially jealous.

I've long wanted to use penrose tiles to make a beautiful game board. Then, I would just have to come up with the game that would use it...

Penrose tiles are the reason I know about him, yet I didn't end up saying anything about them. I was trying formulate something smart to say, and what I ended up saying was related to what he had been talking about. I remember reading that a penrose tiling could be made from a 2d slice of a regularly tessellating 9 dimensional pattern, and was trying to think in terms of "could we recognize an object with more than 3 dimensions by aperiodic tiling". He seemed to be of the opinion that any system with more than three spatial dimensions only applies to the real world if the extra ones are represented as imaginary numbers. But then his explanations are hard to understand, as he seems to be struggling very hard to dumb things down.
