It's interesting...  though Lava lamps require heat to work, so not
necessarily energy efficient.   In theory, you shouldn't really need
the lava lamp part.   Just the digital camera  part.. operate at a
high ISO, say ISO 3000, dark background, and manual shutter and
aperature controls,  configured to achieve exposure with minimal light
(E.g. a lowest possible usable exposure at the highest speed you can
get),  analyze, and discard the value of any pixels that statistically
show as "hot" or "correlated" and capture the inherent CCD sensor
noise due to unpredictability of electrons,  which you maximized,
without having to have any movement in the scene.
