The Da Vinci exhibit is okay. Nice bit of culture, but it didn't wow me. Like other yelpers have said, a lot of posters and 3-D things, some you can play with. I was more interested in the art and the little known facts I read, but my husband liked the 3-D things/engineering side to it. Don't expect a lot and get discounted tickets ($18 each for us) at the discount ticket place so you don't feel like you got ripped off.
