One of the quirkiest devices ever to emerge from Sony, the Rolly "audio entertainment player" rocked and rolled to your music. Two motorized rings around its egg-shaped body enabled it to spin in time to a song played from two speakers mounted at either end of its body. Users could program their own routines and share them online, too. The Rolly always drew a crowd, but few people bought it. Sony released an updated version a year after its 2007 launch, but the Rolly didn't live to see a third edition.
