Dizzy?

This was at the Krannert Art Museum. As you moved by the exhibit, the pattern would change. I wanted to see if it had the same effect as seen through a camera. Not quite, but it still makes me dizzy! (I wish I'd thought to take a picture of the name of the exhibit...I did take pictures of other signs, but forgot with this one and it's driving me crazy now that I don't have it!)
