Audio Visulizations

now, i dont want to sound like an idiot, but i am an idiot as far as processing goes.  what i want to do is to be able to plug an audio source, my guitar, into my computer through the mic input, and then create a manipulatable visual, it could be something as simple as the magnitude of the signal.  but i do need some help with it.  i am a fast learner, so if someone could point out a program that is similar, i could learn from the code, or if someone has a good learning website, that would help me on my quest for a visualizer, that would be great also.  or if you just wanted to do my bidding altogether, we could work as a team, and i could tell you what i wanted out of it, and you could create it. . . that might be asking too much.  well. . please help

have a look at the minim library examples.

http://code.compartmental.net/tools/minim/

especially this one that displays the input:
http://code.compartmental.net/tools/minim/manual-audioinput/

and this one that does an fft transform on an mp3 sample:

(other sound libraries are available, i had trouble getting the others working under linux whereas minim worked like a charm first time)
