Our second (almost finished) invention is a music therapy device. It is designed to help disabled people who get comfort from sound. The Piperdrive is a multi-sensory machine that plays music and sounds. It changes tracks with a tilt switch – a bit like a Magic Eight Ball – but it feels nice to touch, and it also flashes coloured lights. The original idea came from Lucca – and was inspired by his sister. We think it is ingenious. We also think his performance in the video is absolutely brilliant. You’re a STAR, Lucca!
