One day earlier this year, Roel Wouters watched as a friend’s kid set his iPhone on a trampoline, pressed record, and proceeded to use his expensive glass gadget as a video-capturing piece of popcorn. This bit of avant-garde moviemaking got Wouters thinking, and soon he had settled on an idea for his next workshop. His students at ECAL, Switzerland’s premier design school, would have one week to “build an apparatus that produces videos the world has never seen before.”
