“There’s a reason Beck has been so hush-hush about the video for his new single, “Hell Yes.” Actually, there are four reasons. They’re called QRIOs, so-called “dream robots” developed by Sony Japan as high-tech playthings for children. QRIO can carry on conversations, adapt to a multitude of environments and — most importantly — mimic human movements, including complex dance routines. Currently, there are only four working QRIOs in the world. And all of them appear in the “Hell Yes” video.” [via] Link.
