From BBDO Guerrero Ortega comes this sticker that glows in the dark.
As part of their campaign against global warming, the World Wildlife Fund is working with filipino companies to help them become more energy efficient. Often it's the little things that add up, so these glow in the dark stickers were placed next to light switches in offices throughout Manila as a reminder of the importance of conserving energy.
You can see it when the light's on, just barely.
