There’s something a bit spooky about this sculpture of nested, truncated icosahedra in Madson Square Park. The eerie lighting and coloring brings to mind an evil, robotic Jack-o-Lantern.

I like how this piece of playground equipment is designed to demonstrate some mathematics: the braces are color-coded by degree. For example, the blue braces are vertices of degree 6; the red braces are vertices of degree 5; and the green braces are vertices of degree 4.
The color-coding makes it easy to see the overlap of polygons here, too: around each red vertex is a pentagon, and around each blue vertex is a hexagon.
I’m pretty sure this is a bit of cheat as far as regularity goes, but it’s still a nice piece to play with!
