Imagine Cup - mobile graffiti

John Gibby and Peter Pesti of Georgia Tech are presenting their
application called "mGraffiti", which is all about using a mobile
device to apply "graffiti", or personal notes and comments, about key
spots (like your work building, favorite restaurant, hangout) in your
life overlaid on top of sattellite maps.

Very cool, I love the mobile angle on this.
