It's the dead of night ... everyone is tucked up in bed ... the owls are a-hooting. Time to break out the Glow Graffiti! Powered with LED light, you can write, stencil and draw pictures to create your very own glowing light show. It's a little like vandalism, only much prettier. (And the police won't nick you for doing it). Perfect for parties - and if you're nocturnal - it will keep your friends intrigued for hours. How does it work? That's top secret information ... if we told you, we'd have to kill you ... obviously.
