When it comes to DIY projects, there are few surer ways to impress than crafting a unique interpretation of Pong
-- something that's been attempted many
, many times in the past
. Now, a group of students at Cornell University have devised what may just be the most impressive bit of Pong hackery to date, unveiling their so-called "Wall of Pong" for the world to see (and be jealous of). At the center of the system is a moveable laser projection platform that throws the necessary dot onto any flat surface, which the two players can then bat around using actual paddles. From the looks of it, the speed of the ball is somewhat limited by how fast the motorized projector is able to move (check it out in action by hitting the read link below), although it still seems to be capable of providing a satisfying ehough game. Best of all, the entire cost of the project was under fifty bucks, although it sadly looks to be beyond the reach of all but the most seasoned DIY-ers.
