Don’t worry, we’re not going to tempt you to dissect, hack, or otherwise mod your expensive mobile computer. All you have to do to turn your iPad or Android tablet into an ’80s-style arcade game is get your hands on this stick-on mini-joystick by (who else?) ThinkGeek. Wired explains how the device works: “Press it into place over the onscreen controls and the milled aluminum stick will transfer your jerks and tugs into virtual finger-presses by way of a conductive foam pad beneath.” You can pre-order now to get your Pac-Man on at the end of January.
