It's interesting... though Lava lamps require heat to work, so not necessarily energy efficient. In theory, you shouldn't really need the lava lamp part. Just the digital camera part..
You didn't read the whole page. On the right side: our LavaRnd^tm Spelled *LavaRnd*, mixed case with 2 a'sReference implementation uses lens-capped digital cameras to produce random numbers. Directly produces cryptographically sound <http://www.lavarnd.org/faq/crypto_sound.html> random numbers. A single camera image frame can typically produce between 340 and 1420 bytes bytes of random numbers.
