"Considering our everyone's infatuation with everything LED is fairly evident, we couldn't help but stop and stare at a Canadian billboard sporting no fewer than 1,500 LED lights, all brightly shining to spread some holiday cheer. But the method to the madness is what's important here, as this particular poster had no direct contact with an AC outlet, and reverted to getting its juice from some 120 pedal-pushing volunteers instead. The DDB/Vancouver project was lit for five consecutive days on behalf of BC Hydro, and was setup to display just how efficient LED lighting really is. According to BC Hydro, the same amount of wheel-turning energy would've only lit up 120 incandescent bulbs, which would've left Rudolph a bit dimmer than expected. The only thing missing, however, was a government-employed robot to crank out a few more miles once the humans went home for the holidays.[Via OhGizmo]"^^<http://www.w3.org/2001/XMLSchema#string>
