You didn't read the whole page. On the right side: our LavaRnd^tm Spelled *LavaRnd*, mixed case with 2 a's Reference 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. jc
