The Boombench is more than just a rumpshaker. Yes it’s a giant speaker built into a park bench. Yes it’s 500 watts of chest thumping, booty rocking bass power. But here’s where it gets interesting: the music is transferred from anybody nearby with a bluetooth enabled phone. So anyone passing by can synch up their phone and play whatever annoying music they have on there right through this piece of street furniture. I’m in favor of blasting a little 4?33? by John Cage.
