I have always wanted to sketch L Kahn's play of light and concrete at the Kimbel Art Museum in Ft Worth Texas. This is a building every architect studies and most love. Kahn was an interesting character and his son created a documentary on him called "My Architect". A coworker and I were working a few miles away and we took our lunch hour here. We only had about 20-30 minutes so I walked in, found a vantage point and went to work.
