Bob's cool random sig thingy

Wow, an update - 2 years and 2 months later. I can't believe this thing still works. I'll probably be moving it to a different host sometime in the near future, I don't think there'll be any issues.
Things are very basic at the moment, but I will update. Email me with any serious problems.
