Round Rainbow

While I don't like any kind of art with recognizable people in it, I do like more abstract things. One of my favorite pieces while visiting DC was Olafur Eliasson's Round Rainbow at the Hirschhorn. The installation consists of a clear torus that slowly rotates while a spotlight projects onto it. The torus reflects the light in various ways to produce a pattern of rainbows as well as cardioids and other shapes. I found this absolutely fascinating.
