I actually noticed these patches of cracks in the asphalt along my walking route last year. I noted how much some of them resembled graffiti and that they might serve as a design reference for surface design. Maybe I should take some pictures or even try sketching a few. But I wasn't very motivated to spend time sketching them, and I kept forgetting to grab my camera before heading out, and no - I do not have a cell phone that takes pictures. But today - today I finally remembered. I've not tweaked these in any way but can see how a little work in Paint Shop Pro might produce images for thermofax screens or patterns for lino cutting. What ordinary thing do you see on your daily route that your artist eye interprets as an interesting design element for future use?
