Fia Kavanagh and I created a version of the classic game Pong where the ball is a pineapple, and players touch pineapples to control the paddles. Fresh pineapples were connected to a Makey Makey, which was sending data to a Processing sketch visualising the game on a screen (with thanks to Robby Collins for giving us a sketch which we adapted).
Pineapple Pong was shown at Science Gallery event 'Grand Stretch', as well as Beatyard Festival and the National Ploughing Championships in 2016.
