This is another photograph from yesterday's trip to the St. Louis Art Museum. Here my son stands illuminated by one of Dan Flavin's fluorescent light installations.

I've always liked Flavin's works ever I since I first came across one in the Tate Gallery many years ago. They are as basic as you can get; essentially no more than one or more fluorescent lights arranged in a geometric pattern and exhibited in the corner of an art museum room or some other equivalent.

They appeal to me because they cut to the essence of what all visual art is about – namely light. I always feel somehow spiritually recharged after bathing in a Flavin display.
