We ran across a small museum of Da Vinci's works and I had to go in. Will has been in a different one in a different part of the city and he said it was similar. It just had different inventions on display. I would love to see more! When we paid for our tickets, we were encouraged to play with the displays (unless there was a sign saying not to touch) and take pictures (as long as the flash was off for the paintings). Score! We had a blast in there.
