Real-world 'Pong' might just beat the video game

If you miss the days of playing Pong with old-school dial controllers but would rather not track down a vintage console or arcade cabinet, today's your lucky day. Daniel Perdomo and crew have built a real-world Pong machine that replicates the pioneering game with physical parts. Despite what it looks like, it's not just an Atari-themed air hockey table. All the eccentricities of Pong gameplay are intact, just in a more tangible (and arguably, far more immersive) form. LEDs track the score, while the controllers are rejiggered hard drives.
