I was thinking earlier about the "sport" of Parkour, and how it's becoming increasingly popular and well-known. And then I thought. What if sometime in the future, Parkour became a generally normal form of transport? What would the streets be like when people choose instead to jump across rooftops and throw themselves into the urban skies?
So then this sign popped into my head. Lots of those little silhouette people that you usually see pondering across Zebra Crossing signs are now leaping, grabbing and bouncing around darkened roof-tops like squirrel-ninjas. What an awesome sign that would be to behold one day...

I guess you can tell that I TRIED to make it look weathered and rusted...maybe I should just turn the density of the airbrush up next time...ah well, i'm quite pleased with the result. Maybe when i'm a lot better at this kinda thing i'll be able to make it look like an actual sign on an alley-way wall.
But if anyone else wants to do that for me...feel free. *hint hint*

By the way, in case you didn't know, a Traceur is to Parkour as a Batsman is to Cricket.
