I'm working on a tube effect that's in a pretty large enclosure, and I'm basing the enclosure design off the big cannon from FF7. I thought it would be fun to add some sort of interesting visual effect to it. I thought about putting an LED bar graph that would increase as the drive knob is turned up simply by using a dual gang pot and putting a CV on one of the gangs to control an LED controller, but there certainly has to be something more interesting out there. Or something that flashed faster as the drive increased, but I have a feeling a simple flashing LED wouldn't too interesting. Perhaps a multi color LED fading between colors.
This is real cool, but probably a little outside of what I could put together. Unless there's a kit for this type tube thing out there:

Thanks for any suggestions!
