He's still around! He hosts a trivia podcast called Lateral.

The lava lamps are just a gimmick and evening filming a white wall (as long as the video is not overexposed) would be just as random/secure because of the avalanche effect of cryptographically secure hash functions and the thermal noise of cameras.
