I spend a lot of time at Mathworld looking at some of the amazing interactive geometry examples therein , and wishing I had the time to learn to do similar things. So when I come across someone who has built real-world versions , it makes me want to hang up my programming spurs and find work in the food service industry.
Nah, not really. But BOY would it be cool to have one of those.
