This is what you'll need:
- line laser (http://dx.com/p/red-laser-module-focused-line-3-5v-4-5v-16mm-5mw-5928?sourceSKU=46389)
-bare bones clock (either buy on online or take apart an old one)
-cover (I used a little plastic cover I found lying around, be creative)
Step 2: Cover
Spray paint your cover and attach it to the clock. I actually attached mine to the wall independently of the clock, but either will work. If you don't trust your judgement on where the arm is pointing exactly, you can attach numbers to the wall....be creative!
You've done it! This was a SUPER simple instructable that yields an amazing result and look.
