proposal still in progress...

At this point I'm still trying to figure out exactly where to focus on my project, at this point I know that I want it to involves either GPS or paint along with skateboarding, I'm interested in illustrating the motion of skating- the GPS tracking of someone skating a single spot going around certain obstacles in a smaller space like a skatepark. I'm also inerested in the physical tracks of motion such as the marks left behind from wheels and trucks wearing away at a certain obstacle, or the lines of dirt that are tracked on wood or walls similar to a car's skidmarks, I'd be interested to see what wheels covered in paint would create.
