CLOSED: Thanks to all who participated. Congrats to JeremyThroopityThroop, for the following idea: "Put them on the steel wheels on your car (toward the inside so they don't fly off) so they make cool circles while you drive."

Yay, it's Giveaway Tuesday! And this week's prize is... AWESOME.

ENTER TO WIN

From ThinkGeek, a 40-piece kit of magnetic LEDs for digital graffiti, AKA "electronic tagging for the masses". Battery powered, the LEDs will stay lit for up to 48 hours, and come in red, blue, green, orange and rainbow.
