The visitors can play an augmented reality pong game, hitting a virtual ball with their own hands. During the game, the player's gestures are translated into actual drawings. The drawings, painted on a real ping-pong ball in real time, giving each pair of players a unique souvenir with a physical manifestation of their own game.
For this Art installation we've used the EggBot, by Evil Mad Scientist Labs. However, the original Bot needed several modifications, including a second pen arm assembly, some LED lights, and mainly, an automatic ball-loading mechanism that selects one ping pong ball at a time, feeds it to the egg-bot, and ejects the ball when the game is done.
