Dominic Wilcox has created a fully functional prototype pair of shoes that will guide you home no matter where you are in the world.
A little piece of software was created to plot your preferred destination on a map. This is then uploaded via USB to the shoe. The GPS is powered by a battery similar to those found in mobile phones. The data from the GPS in the left shoe wirelessly communicates with the right shoe which shows the progress made on a row of lights.
