Sure GPS units are great to help you get from point A to point B, but did you know that they can also be used to draw pictures? The GPS drawing site is an amazing collection of images that people have drawn on land, air, or water, using a GPS unit. The above image was drawn on a 67.7 km bike ride through Brighton by Jeremy Wood. The images are drawn in all sorts of ways including by dogs in a park, guys with lawn mowers, someone putting down the chalk markings on a football pitch, walking on the beach, and many more. My favorite part about this is imagining how awesome some of these people must look walking in circles with a GPS unit in their hand!
