This is without doubt the biggest music box i have ever seen.
Commissioned by the Cleveland Institute of Art and developed in partnership with Ohio CAT, [‘The Music Box’] sees the american artist dismantling a 22, 000 lb steamroller in which he refabricates more than 80% of the machine–though still maintaining its identifiable physical qualities–transforming it into a fully functioning musical box, and at a fraction of its original weight. Built onto the front of the compactor is an acoustical cabinet made from cherry wood.
In the below video you can hear what it sounds like, and what it looks like in operation. It doesnt sound that nice actually, but just the fact that somebody made this is pretty amazing.
