Mark this under the category of art that would be fun to replicate...
Take a large sheet of paper or a canvas (similar to what I did here) and just start painting circles or triangles all over, layering them on top of each other as you go. It can be done with a paint brush but I think it would be better drizzled onto the canvas.
I am so into abstract art lately and am itching to try this now, too!
