Idea for infinite sustainer / feedback

This is so simple and cheap and it just might work.

Have you ever seen those?  They supposedly turn any surface into a speaker.  I heard that they're not very good, but I'd love to get one to stick on my guitar.  I remember reading about a DIY project about sticking a small speaker on the back of your pickups.  Anyways, just an idea.  Since I live in an apartment, I'm hoping this may simulate the interaction between guitar strings and sound waves from a cranked amplifier.
