Gizmodo notes that LightLane, a product designed for a competition by Somerville product design firm Altitude, is being manufactured.
LightLane is a small LED projector that attaches to a bike under the seat. When switched on, it projects a green, luminous bike lane on either side of the bike, the authority of which Boston drivers will doubtlessly respect.
Ironically, Altitude is located in the one place in the Paris of the West where you may not need a LightLane — on its bike path.
