I think my favorite observed application was a series of them used as
touch-sensitive switches for preset station selection in a mid-1970's
Sherwood FM tuner.
It was the type of app that might get mentioned in some book or article
as an idea, but not likely to be used in real-world production. I kind
of wonder how they stood up in those FM tuners in high-static
climates/environments.
I only ever used them for audio noisemakers and
LED blinkers until the
past year or two when I started dabbling in PWM. I read all I can
find about them and learn something every time I do - the on-chip
design may be simple, but the the applications are myriad and complex.
It really is an amazing circuit.
