Cyberpong was a submission to the start-up Uberpong as part of their kickstarter. The client approached me asking for a piece of original artwork that would be printed directly to a ping-pong paddle and sold to the public, with me recieving a share of the profits. This was the final piece, though they ultimately only used the Red version.
Unfortunately, the paddle is no longer available for sale.
