Behold, the official shirt of DEF CON 19—the world’s preeminent event for hackers. The Electronic Frontier Foundation solicited the help of charitable art project Robots and Monsters to create the special shirt.
As you can see in the image above, secret codes glow in the dark when the shirt is worn in darkness. It also reveals hidden messages when placed under a black light.
Unfortunately, you’ll actually have to attend the event in Las Vegas to get your hands on one. The show starts tomorrow August 4th and runs through the 7th.
