Any idea where a diagram would be or how I would go about making one that would run symmetrical across the top of a 36" box? Lol.

I am a noob at circuit design, but I have worked with resistors and thermisters and have a lot of books about circuits so I might be able to figure it out. My goal was to make a very inexpensive, customizeable circuit with readily available parts. Most of the kits that you buy come with a pre-programmed chips, or blank ones that you need to program, so they are essentially digitally controlled. I would like to create an analog one if possible. If anyone here has any experience in circuit design, chime in and we can make this happen!

I'd say something with a sound input, then branch it off to sets of VU meters at different frequencies? I was thinking about something like that...
