It's ironic that this is basically a Borg mood light. After all, if a Borg drone experienced intense emotion, its auto shutoff mechanism would kick in since this was "interpreted as a sign of disconnection from the hive mind." So basically, don't get too excited over this Borg cube or you might have those higher brain functions shut down. We've named this the "Star Trek Borg Cube Glowing Chair," but it can be a lot of other things if you don't feel the need for glowing illumination on your butt...
