I've heard stories, my dad went there in the early 60's as a physics major, dropped out and then got a PhD in asian history from a different school, then lived in Japan for a while, taught university history for a while, then came back to the US and became a computer programmer (Cobol mostly) until he retired. He told stories like that but I didn't really believe it until the movie "Real Genius (1985)" put it on film. From what I hear, the pranks in the movie are lame shadows of the real ones but it's a movie and it gets the vibe across for me. Trying to understand my dad a little, that movie helped. Anyway, Caltech sounds cool. And the guy living in the closet would be doing crypto or AI now. :)

His last project was trying to write a comprehensive history of Japan for wikipedia. I helped him upload it and it's buried in Wikibooks somewhere now and I like to think that some of his work is going to end up in the training material for some future AI like a ghost.
