Pilot Error and Space Invaders

Here's some fun research into human behaviour & mistakes using Space Invaders as a research tool: cs4fn: Pilot Error and Space Invaders. I've mentioned it because a similar approach to this was adopted by an M.Sc. by Research student here in 2002/3: He created a random web crawler where the crawler derived its random sample from users of a Flash-based front-end Space Invaders game where the invaders represented web pages to be crawled when killed (as described in this publication).
