iPhone 20

A hand-drawn phone on what looks like an ordinary post-it pad gets introduced as cutting-edge technology — the iPhone 20. A packet of sample PIN codes is riffled through, and the spectator calls stop wherever they like, memorizing whichever four digits land next. The performer never looks. Then the "phone" comes out of its case, the spectator imagines typing their PIN in, and one by one the numbers on the screen vanish until only their four remain. Daniel Chard's iPhone 20 — watch it and see for yourself.
