Randomizing Emission Colors in Cycles Render

Hello everybody,
This is my very first post. It is about my first tutorial on Randomizing Emission Colors using One Material, across Multiple Objects in Cycles.

This is my very first tutorial so please go easy on me. Also, let me know of anything I can improve on, things I missed/didn’t explain properly, etc.

Furthermore, please let me know of any tutorial requests you guys have and I will do my best to fulfill those requests.
And please let me know of any better screen recording and editing software besides Camtasia Studio 8. That would be great.

Keep in mind that I filmed and edited this between 1:30am and 3:30 am (That was the only time I had free to be able to do this)

Thank you very much.
