Like Rothko, Albers and Pollock . Reich and Glass . Art that is continuous and homogeneous. Art where you could miss a little and not miss much. Art without discernible architecture.
Nothing really happens.
Screen saver art. Something to observe while you're vacuuming. Calling it Lite Art is cute, but misses the point. Outwardly simple things are not inferior to complex things. A beautiful blue sky has a majesty that the Sistine Chapel just can't beat.
