The patterns in this macro photo remind me of a tire tread, so I am guessing that it is not a photograph of a tire tread.
Is it a photo of one of those foot mats to wipe your feet when entering a building?
My other guess is that it is part of a treadmill or other exercise equipment.
p.s. I really like some of your other articles giving tips on macro photography. I am just starting to figure out how to take macro photos with my new digital camera and it is really hard with some subjects.
