Virtual Geoglyphic Adventures. That is what WallyGPX.com offers to visitors, an online tour of images created from GPS tracks.
Michael Wallace has been designing bike routes based on everyday people, places and things for a few years now. In the beginning he was riding "blind", only able to see the fruits of his labour, the word or image, after the ride was completed. Using both road networks and parks Michael was able to create trains, planes, amphibians, rodents and many other interesting outlines using only his ingenuity, a mountain bike and a GPS.
The city of Baltimore has been the backdrop to the majority of Michael's works of art. We encourage everyone to try this in their own city, and share your tracks with WallyGPX via Twitter. To see more of WallyGPS art visit his website or Buzzfeed page.
