Joshua A. Horowitz ’10 (right) tries out “SNGH Is Not Guitar Hero.” The game, created by Rhys A. Hiltner ’09 (center) and Ruth A. Shewmon ’08 (not pictured), evaluates the user’s playing on a standard electric guitar. Shewmon compared it to the game Guitar Hero, except that “once you learn a song you can play it on any guitar.” Eta Kappa Nu, the honor society for Electrical Engineering and Computer Science students, held the annual Expo yesterday afternoon in the Vannevar Bush Room.
