Grafitti (or is it)?

These are really awesome metal sculptures made to look like graffiti on the walls behind it.

This one's the hardest to see, but still pretty rad. Graffiti the sky!

This was some of the art along the Highline.

And below is one of the coolest wall paintings that we saw.

These are all over NY. I think because there's not that much sky space for billboards...
