"Levitating Mass" a.k.a. "The Rock"

[otherprof]

This is a permanent installation (try to move it!) at the Los Angeles County Museum of Art. You interact with the boulder by walking under it. I've taken hundreds of photos of this artwork..

A nice shot but it's not levitating, it's resting on the two walls..?

Right you are! But that’s what the creator (artist?) and the museum call it.
