Can someone help me create a script to make a moving disco laser?

I need some help making a moving disco laser for a club game. I have seen them before in free models, but they don't actually 'Randomly Move' they just move like 3 studs and move back and repeat. Can someone help me with a script that will make it actually move randomly? Or at least close? Thank you if you can.

We will not "help" you make a script for you. We will only "help" if you are stuck on making a script. This isn't a request site to get us making a script for you. If you really need help with your script, then all you have to do is post it and tell/show us the problem.
