Lights off

Perspective can sometimes be a matter of night and day.

So that people aren’t in the dark about Earth Hour on Saturday, the World Wildlife Fund teamed up with The Viral Factory U.S. and Brit electronic band Hot Chip, to create this animated spot. The cool part is there are two storylines: a lights on and a lights off version. Which one you see depends on the amount of light your webcam detects in your room. Of course, if you don’t have a webcam you can manually switch back between the two storylines by clicking the virtual light switch in the upper right corner. Spaceships are cool.
