Some friends and I were talking how cool it would be to have a multiplayer scavenger hunt app for our phones that used gps to see where things were. We started playing around with Joyity (free in the market) which is a pretty cool idea and gives you freedom to create your own game scenarios etc. There's a hunter mode where you get assigned someone to catch and someone is assigned to you. The problem is, only a couple of us have android phones, and no one seems to be around when we search in joyity (California). If anyone has been looking for something like this, check it out! Or if you have other suggestions for similar apps let me know
