Cracks In The Sidewalk

I've always taken cracks in the sidewalk for granted until I saw an exercise in my Drawing Lab book that talked about drawing pictures of cracks and then morphing them into interesting plants or animals or other things. I felt like an idiot taking photos of cracks in the sidewalk as people filed by, but I really like the way they came out. I even wrote a poem about it. So I've either had an epiphany or lost my mind all together.
I also found it interesting to study the things that have migrated their way into the cracks.
