I once read that noise of camera in total darkness is apparently a good source.

Would a CRT TV tuned to channel 3 and no RF input be a good source?

You can already have a good entropy source from a single resistor.

The noise probably makes the lava lamp wall just as effective as pointing the camera at the Mona Lisa - the lamps themselves are not that unpredictable frame-to-frame.
