Photoshop Tennis is a fun little game played between graphic artists, in which the artists take turns adding layers to a Photoshop image, each layer an attempt to outconceptualize the last. The Dane recently wrote about it, ending with an invitation to challenge him to Tennis. I issued a challenge. He accepted. As of today, I served.
