Hiptop Nation is a blog forDanger's Hiptop owners. They recently had a Halloween Scavenger Hunt. Smartmobs blogs about it and one of the members of one of the teams has written a paper about it.

Teams, games, wireless devices, photos. Cool stuff for blogs moving forward.

Speaking of games, although this is a bit old, I thought Survivor Blog was very cool.

We have a lot of different wireless devices in Japan that let you take pictures and email them. We should try to think of some cool games too.
