Lavarand is a really clever random number generator produced by some folks at SGI. It's based on some sophisticated numerical twiddling with gigantic prime numbers, but it uses real-time digitally captured images of lava lamps as its basis.

So I went to their "play with random stuff link, and from there I asked it to pick me some lottery numbers, and 37 was the very first one on the list that was returned. (The rest were {45, 40, 32, 2, 5, 8}.)
