Proof, if ever it were needed, that it's execution not the idea that's important. No doubt there are others too, as I have a half-backed prototype of pretty much this idea (including Amazon integration), however it's nowhere near finished (it was a Rails learning excercise), and even if it was, would never have looked half as good as this. Nice work!
