LED lit guitar strings and frets

I want my guitar to light up where I touch it on the frets, and light up the string that I pluck as well. It could be a simple light, or it could be done cooler with a pulsing light that changes according to the frequency of the note. It would look awesome when you shred with your electric guitar, and you could see what notes you were playing if you were not yet skilled enough to shred.
