Pot resolution - dithering

How to change the resolution of a pot to dramatic levels?  I'm talking
about beyond the resolution of the adc, and over time spans of say a
second.  Add a little white noise that crosses the 1 bit threshold.
How to do that?

Maybe just using hum or other non-white noise present in the system is
already enough as long as the _sampling_ is done randomly to avoid
creating correlations (beating).
