Do you have the physical endurance of Cadel Evans and the creative genius of Picasso? Michael J. Wallace has found a neat way of combining both of these talents, all while getting the daily dose of fresh air and outdoor exercise that we so dearly need. Wallace creates bicycle routes in his hometown of Baltimore, and then rides them with the accompinament of a GPS tracker. Amazingly, all of these bicycle routes are in fact pictures. So as he pedals along innocently down the streets of B'more, he is in fact drawing his very own geographical masterpiece. Collected in the website WallyGPX, he's drawn and rode some characters and scenarios that are impressive in their complexity. These include a man surfing, a semi-trailer, and even a depiction of the landing on the moon. Given that one wrong turn could effectively ruin his canvas, you've got to appreciate this man's ambition. Do you have the energy and skill to create your own artistic bicycle or running routes? Give it a go in your hometown, and see if your friends can guess what picture you've mapped out. In effect, this could become a game of Draw Something - but way harder and infinitely more awesome.
