Stairwell Stock 10

I decided to take random stock-type pictures in one of the stairwells at work, and this is one of the results. I find the concrete in this stairwell interesting because of the designs in it.

This photo can be used as stock in photo manipulations, backgrounds, and other things IF, and only if, credit is given to me.

Linking finished works that use this photo is encouraged. I love seeing what people can do.
