Apple Karts are small machines that translate the sound from an iPhone to drawings. One can draw their favourite song or give commands to the Apple Karts by singing into an iPhone. Apple Karts are physical apps, which take advantage of the iPhone and link it to the physical world. The project leaders were researchers Elio Caccavale, Jon Rogers, Pete Thomas and Mike Shorter. The project was exhibited at Il Compasso Di Latta in Milan. I helped manufacture the electronics as well as the card chassis for the devices.
