Photoshop Tennis

It's a pretty simple idea, really: One player emails a Photoshop document to the other containing a single layer. Each player progressively adds a layer until the match is over, either by time, withdrawal, or mutual consent. A guest adds comments in real time and the people watching vote for a winner. - Read at G4

Started by Croudal Partners, this deceptively simple concept sounds like a sport I would definately be interested in! It's taking the design community by storm, and is a fantastic way to promote creativity, collaboration, competition, and plain old fun.

Begin with a randomly chosen image or set of images, and start the game. The artists take turns manipulating the previous layers, and adding one new layer to the mix. The only rules, are that you can only add one layer, and you can't completely cover the previous layers (so you have to use elements from the previous rounds).

Anyone have any ideas on how to use this as a ministry/evangelism/discipleship tool?

I'd love to give this a try if I can find anyone as crazy as me.
