Gattina's Photohunt theme this week was Graffiti/street art and Sandy's Photohunt theme was flash. I'm going with the street art option in combination with the flash theme, although this is actually sidewalk art.
The un-doctored shot above looks to me like flash photography although the sun was the flash. I played with it below to reduce some of the sun's flash.
As you walk along on this sidewalk you pass by eggplant, corn and other vegetable graphics in a flash. The eggplant has a flash effect from the sun which looks like an exclamation mark.
