http://www.chatroulettemap.com is a gateway to pure evil.
Take the seedy Chatroulette site, write a bot to iterate through potential flashers, log the IP address and match it against a GeoIP database, and plot it on Google Maps with a screenshot.
If I were a troll stalker or this troll's poor mother, much drama would ensue.
This is much, much more interesting than Chatroulette itself.
