I was playing about with writing to the framebuffer in C to allow me to draw a waterfall from rtlsdr.
This is about the simplest way of getting the spectrum plot of signals from rtlsdr using FFTW routines.

Hopefully someone else will find this useful, it's just what i was looking for initially but never found anything useful on google!
