That was it for classes. At 6:30 I joined something called Mobilizer Madness. It was a scavenger hunt, powered by PocketPCs connected to the network somehow. The PocketPC asked questions, and our team of 7 people had to run around the convention center and answer questions. The device worked great, and the game was fun. You got points for how fast you answered the question, and how many tries it took.
One of the questions was: “The phone company wants to create a system where if you mis-dial a number by one digit, you will still be connected to the correct number. If the numbers are always 10 digits (000-000-0000), how many possible unique phone numbers are there?
Some of the missions involved tracking down a secret agent somewhere in the building, and completing a task. So there were game 'actors' around the place.
Out of something like 15 teams, ours...won! Here's our team before we found out we won. I don't have a winning picture...

Clockwise from top is Me, Kip, Hector, Lowell, Karthik, Ken, and John. Awesome teammates!
This was run by a group called The Go Game. They do corporate team-building stuff, and some public events. It was very fun. Try it out if you ever get a chance.
