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.
