Interesting. I wonder how true it actually is that they use it like they claim here: https://www.cloudflare.com/learning/ssl/lava-lamp-encryption.... It's in one of their lobbies, so doesn't that make it susceptible to an attack in some way? I'm not knowledgeable enough to know, but I figured if they actually used that method, they'd have a more controlled environment.

I also don't fully understand it. A large part of that wall is static. And the camera isn't going to pick up on the stochastic properties of the lava as much as exists in the real world. So it feels like their images will be very statistically similar.
