Neat.

Mere and I do a lot of urban bike riding here in Denver. The bike culture is quite present, comparatively, to living other big cities (ahem, Atlanta, you could learn a thing or two about being bike friendly). There are an adequate amount of bike lanes and paths and ped bridges, but still, occasionally when you're in the heart of downtown, cars get RIGHT up on you. I get it, though, it's hard to always make room for everyone (thank god the sidewalks here are are never full besides rush hour and you can always poach one).

Seeing as how many of us fossil fuel non-users (i.e. bike commuters) are still in danger on the roads, the people at Altitude, Inc have created LightLane. It basically projects a bike lane around you as you ride. Best part: it uses Lasers (say 'lasers' in your best Dr. Evil voice). In theory, this gadget provides drivers with a boundry to stay out of when dealing with bikers. Read about it here on Good magazine's blog (Good mag is very cool, btw).
