The Le Corbusier retrospective currently at the Netherlands Architecture Institute is a must-see if you're interested in architecture. It covers every aspect of Le Corbusier's life and work. Among the exhibits there are some real gems. By this I don't refer to the pebbles from Le Corbusier's private collection, but to some of the items that are rarely seen together in one exhibition.
I love this video. There's so much joy in it.
