On-Line Composition Class

I'm taking an on-line composition class titled Dynamic Composition.  The first assignment was to use a very restricted color way and only to use squares and rectangles.  I went to a Joseph Albers book for inspiration and basically copied 4 of his designs. The teach said - keep trying.  I liked this one in its simplicity.  So many of the other students glommed on so many elements - I thought mine was pretty pure!
