Well, I haven't made one of these for a while so here's a "K" series improvisation. The "K" series is based on the idea of visual improvisation on the model of modernist artist Paul Klee. These are done in purely digital media, which is a lot of fun to play with, like an infinite set of "Colorforms." You may remember these enchanting visual toys where you put the colorful plastic shapes on a shiny black background. If I had to do this design with paint it would be a big job even for a small art piece. There is an image of a tomato in the picture which was my original inspiration, a red square the color of a tomato.
