The above link is an old electric meter box that I found in downtown Boonville, Missouri. The aged and weathered look of the paint on it caught my eye as did the contrast of the color of it vs the color of the nearby gutter shown in the image.
The above images are photos I shot of the texture on the side of an outdoor freezer. It is one of the old walk in freezers that are typically stored outside of the building for cafeterias, school lunch programs, restaurants, etc. Some parts of this image might make an interesting bump map or texture map in a 3d modelling software.
