The good stuff starts about one minute through!

These two pictures are of the University of Michigan Museum of Art, designed by Allied Works Architecture. I like the contrast between the thin concrete slabs and the glass behind it. The vertical slabs give texture to the building's surface and interplay between light and shadow create a sense of depth. There is even repetition in terms of spacing of the slabs. The rectangular slabs are increased in scale to produce the glass windows that allow outside observers to see the tapestries hanging down from the ceiling inside the building, inviting them to enter.
