If there's one thing we love about DIY projects, it's the feeling that the outcome is more than the mere sum of its parts. This here binary clock is a prime example, being composed of scrap plastic, some dirt-cheap parts and a homemade Arduino board. And yet, after a few licks of polish and the inevitable LEDs, it looks like a true monument to geekdom, which is only amplified by the fact you can't even use the thing without being familiar with binary code. But then again, if utility was a standard by which we judged homebrewed projects, we'd have a lot less to talk about.
