Wow, superstar judges.<p>Here's an idea for you android developers out there.<p>Build a scavenger-hunt type app. get people to check-in to places, city halls, museums, parks etc (educational stuff?) and they submit picture to prove it. Earn Karma points. Give them a calorie count for fun<p>Also let users build/design scenarios for other users.
Companies will love this too, get their staff on their feet and moving.<p>I'm a UI guy, if you need my help.
