How many of you played with lego when you were young? Did you ever want to build something really amazing but found that something was lacking? If you did then you should have a look at this site that I found on Green Fairy's linklog.
This guy has built various mathematical surfaces from lego blocks and some of them look amazingly intricate. I'd like to see him try a Riemann Surface, though. ;-)
Anyway, what was the best lego model you ever made?
