I stumbled across another one of those pointless but nonetheless fantastic Japanese inventions: the Rolly by Sony. The video above shows the device in action, the video below is mostly an interview with one of its creators. I’d first heard about the Rolly concept about a year ago and though to myself, ‘Why would anyone want a music player that rolls?!’ But I have to admit that after watching the video clips, it is indeed pretty cute…. I just love the way they programmed it to mimic animals!
