I tossed together a simple site for posting up signs and billboards that you may encounter when walking through town, driving about, etc.
This is an experiment to see how long it takes to get lots of images from all over the world.

I am hoping some clippers will post. Note that this site is cell phone enabled, so once you create an account, there is information on there on how to upload from your cell phone. Please let others know. Would be cool if someone could get some from Times Square.
