A Finish company named Unmonday designed these white hexagonal ceramic speakers that replace buttons with orientation-sensitive controls. These speakers can connect to one another wirelessly by being rolled onto different sides. Up to five unites can be combined to play in sync when connected to a TV or computer.
The Unmonday Model 4.3 speaker has one button to turn it on; other than that, the controls are all orientation-based. If more than one speaker is present, the user can rotate the devices to synchronize them. If you want to mute a speaker, just turn it on its head and the sound will stop.
The case is from vitro ceramic, has a handmade grill and has a charge point on the back of the device.
