Here is a series of photos, inside the other small rooms and walking through the exhibit as a whole, that will give you a sense of the experience. The white room with the colored dots in the first pic is the only interactive part — in the rest, we were carefully reminded not to touch anything. But in the white room, each visitor is handed a small sheet with a half dozen dots of different sizes and colors. You get to put your dots anywhere in the room, to fill out the white space. It was a lot of fun.
I don’t know where the exhibit is going from here when it leaves Seattle early in September, but if you have the chance to go, don’t pass it by.
