Mark Jenkins: Street Installations

I know very little about installation artist, Mark Jenkins. After recently coming across some of his work, I couldn't resist sharing it. All of the photos I've included of his pieces were displayed in one of three locations: Washington, DC, LA, or NYC in 2006 or 2007. Since some of you live in these areas, please let us know if you have seen any of his work or have any additional information about him (as of now his website doesn't include a bio). If you are as intrigued by the photos of his work (he kindly let me "borrow" them from his website -- not exactly-- but hopefully he won't mind the free publicity) check out the other projects he is working on.
