Hullo there.
I am fiddling around with Google maps, making a map of caches we've found for my website. However, I'd like some icons for the map so I can differentiate between cache types, and the Groundspeak ones we know and love () are copyrighted.
Does anybody know of similar images that are in the public domain / released under a GPL or Creative Commons license? Failing that, are there any graphically talented people here that might volunteer to do a set of icons?
