From the bright minds of Britain’s answer to ThinkGeek, Thumbs Up is selling a T-shirt that is sure to entertain anyone with a 10-second attention span. A white-board style panel centered on the cotton tee lets you write offensive messages, draw lewd photos, or scribble whatever you please, then lighting up your doodle via a pulsing strobe beneath the panel.

Perfect for geeks, ravers, and gag gifts, the T-Sketch is available through the U.K. site for £30, or about 60 bucks. It runs on two AAA batteries, and though the site will ship to the U.S., we doubt you’ll want to shell out the extra £33 for shipping (giving you a grand total of about $120). To get some flashy shirt action, ThinkGeek does have a few, if less versatile, options.
