I love guerrilla advertising and ambient media. This piece in particular shows just how clever they can be and how simple ideas can grab peoples attention and inform them of a product or message.

Move is a brand of lighting for bicycles, they have used glow in the dark stickers to promote their brand. Not only is the position of the stickers brilliant, they remind people of the importance of good lighting on their bike when the glow in the dark substance is activated at night. Genius.
