tptacek is right. It's a cool art installation, but for practical purposes this is utterly useless. A modern hardware RNG (which is entirely silicon based) generates random bits at a vastly higher rate, and with better reliability, like built-in continuous statistical tests, than something rigged together with lava lamps, Geiger counters or the like. I've built those kinds of science projects, and they are great for fun and for learning, but they are not practical or necessary in any production environment. |

But do they provide any greater advantage or greater utility to your "science projects" other than being cheaper to run? What do higher rates and higher reliability have to do with being able to create a non-deterministic and thus truly random bit? In other words, how on earth would a hacker even conceivably be able to hack the lava lamp setup?
