If the information encoded in the lava lamps is not important for the entropy, why do they even need to be there?

If it just needs to be some image, and it doesn't actually matter if others know what it can see, why not just point the camera at a normal lamp, or an empty room, or the sky?

It is, the author is just saying that even without it they still have enough entropy in the system to be secure enough.

Any old image doesn't have pretty strong random number generators in it.
