Here’s a fun and stylish project you can make from discarded RC car parts and dollar store laser pointers: an Arduino-powered laser clock. Using easily sourced parts, including a Blanda Blank stainless steel salad bowl from IKEA, over-blogger @ Zouliv wired up a couple of lasers to an Arduino to tell time. The left hand tells time by the hour and the hand on the right by the minute. Schematic and suggested hour/minute decal placement are available here. [via IKEAHacker]

That’s an interesting project but unfortunately it doesn’t show the time in the normal way:

Also, I find that the Arduino sucks at keeping time. A nice side project to this would be to use and ethernet shield with a ntp client on the arduino to keep the time in sync.
You can get very accurate timekeeping out of the arduino by calibrating it. That’s how your digital watch keeps good time— through calibration.
