If you're at all into design and/or web development, I think you'll get a kick out of this. Good way to get some entertainment to punctuate your Fridays at the office this fall.
All about Layer Tennis. The gist? One designer "serves" by sending a design over to another designer. That player volleys it back, having played with the design in photoshop, built upon it, changed it entirely while maintaining the central theme, etc. It goes back and forth every 15 minutes till the match is over, but I have no idea who decides that, and when.
Anyway, the first match is
going on right now, and it's pretty funny. If you're on Twitter, I suggest
following the action that way.
