This is a game of image pong using iPhones, an instant messageing app called Kik, and a companion app called Sketchee.
Working on the very small scale of the iPhone screen, and even smaller window of the app, with very basic one line thickness, in black or white, this was quite a challenging game.
The game was being played three ways between artists Derrick Welsh, Karen Wallis and myself in the spring of 2012.
