Colourful Streets

Contrail was designed for cyclists to leave a thin line of chalk on the road to mark out safe cycle routes for fellow cyclists to follow and as the lines get thicker this shows cars the path. The design was created by Pepin Gelardi who's main priority was for the safety of cyclists but had turned an ordinary push bike into an art tool allowing the rider to create their own lines and for others to add over making the street one giant canvas.
