This is an interesting writeup of an alternate-reality game called ILoveBees, that is dovetailing with the Halo 2 plotline.

Check the authoritative web log for more info on this reasonably involved and pretty neat game.

The thing that gets me is how intense some people are in these things. One guy went to answer a pay phone in Florida during a hurricane just so he wouldn’t miss part of the puzzle. The person who called the phone just said “dude, it’s a hurricane, put the phone down!”. Which, I have to say, would be a pretty big let down after risking your life to be there. The phone, by the way, was destroyed shortly thereafter by the wrath of nature.
