This bargraph generator looks like it could be useful!

I watched the video, but I wasn't able to work outwhat all the user input was for - what I'd like a bargraph generator to do is react to an incoming analog signal.

Ideally with just 5 leds... up until, now, I've been using a dedicated bar graph IC ( - warning turn your PC sound down), but the problem with that IC is that it's a one trick pony...therefore I was thinking of using a PIC to do the bar graph - becuase this would allow corny LED patterns like Knight rider etc!...so I was pondering how to do this just a couple of days ago...this thread is very convenient!
