Besides being cool, I do this intentionally to celebrate the lava lamp’s role in keeping the Internet secure! According to Wikipedia, “Lavarand was a hardware random number generator designed by Silicon Graphics that worked by taking pictures of the patterns made by the floating material in lava lamps, extracting random data from the pictures, and using the result to seed a pseudorandom number generator” (Lavarand).
