how do I make a sound reactive for anything to plug into?

Hi, I have seen many different types of sound reactive adapters, but I am looking to make something that is kind of like the "clapper" where you can plug any appliance into and then is sound reactive to music.  Now for example, if i wanted to plug in some Christmas lights, or a tube light into a plug adapter where it would light up to music.  I have cold cathodes that use the 4pin molex on my computer. if you are familiar with those, I am looking for the exact same effect except for me to use with a standard plug.

Look for 'color organ'. It's a circuit that's been around since circuits could switch current.
