My son and I toured the California Science Center in Los Angeles in May last year. They have had an outstanding Leonardo da Vinci exhibit which, unfortunately, closed January 5 this year. There are still lots of web pages about the exhibit up.
Horrifically bad was the IMAX movie "Cities of the Future 3D." It was nothing but progressivism and climate crap on steroids. It was as far from the grandeur and brilliance of da Vinci as you could get.
