There are many art, nature, and science museums within walking distance of us in Houston. On Sunday we decided to take in a few of the free exhibits and could not have been more pleased with what we found. At the Contemporary Arts Museum Houston the featured exhibit is Marilyn Minter: Pretty/Dirty. After seeing the exhibit we thought we would try to find the Rothko Chapel which we knew was in the neighborhood. Walking through the St. Thomas University campus, we happened upon one of the campus security personnel who told us about some other great free art exhibits on and near the campus. One we were unaware of was entitled "The Infinity Machine" and is displayed in the Byzantine Fresco Chapel. This was an amazing immersive visual and auditory experience featuring a rotating mobile of mirrors and the sound of the interaction of the solar wind with the earth's magnetic field. After "The Infinity Machine" we found the Rothko Chapel and after that had a little time to visit the Menil Collection. In particular we enjoyed the exhibit of the late work of Barnett Newman. Unfortunately we did not have enough time to see everything in the Menil Collection (perhaps another weekend), though we did take a few minutes to relax at the Menil Bistro before walking home.
