These days the video entropy source is not a lava lamp, but a lens cap - in the dark, the ccds generate significant thermal noise, which (unlike chaotic noise) cannot fail, unless someone immerses the camera in liquid helium.
Do you (does anyone) know of any papers that have formally analyzed this entropy source?
