Random artwork

This is my random artwork of the week. I used polyline to create it. All you have to do is drag polyline over the other lines, then when you have finished, you have to join your two starting lines together. It sounds really confusing, but it's not.
My favorite part was creating the different shapes. The most challenging part was making it all fit onto the google drawing. To be BTB (better than before,) I could have made more shapes, or written a bit more about it.
