The Lego contraption was built as an analogue GPS unit. It has a 1.6m roll inside which includes images. If it's dark then LED lighting will switch on to give you a better picture and there is a plastic cover over the top so rain doesn't damage the images. On the downside, it's just a single route from someone's home to school in case he gets lost. Still quite unique though and I must admit, quite creative.
