In Illustrator, I have used the pencil tool and drew a curvy and overlapping line. Then I put a box around it and then used Pathefinder tool to divide into different shapes.
I used the color palette to color each of the shapes in the image...bleh!
After playing with the lighter colors, I found a very abstract image and re-colored the image accordingly.....what do you see? And no, bleh! is not the answer!
