I love how they're sending 'true random' over the internet.

'True random' can only be sampled, it cannot be generated, as TeraTask seemed to hint at with the comment about ordered systems producing unordered results. The cheapest, most cost effective way for the average user to have a sample of random data is to buy a sensitive microphone and record noise from a room with an oscillating fan blowing. Some magic applied to the variances in sound and voltage and you'll have a 'random-enough' generator.

(Yes, the fan is oscillating. No, the random noise isn't coming from the fan directly. The fan just keeps the air in the room moving across the transducer in the microphone, which is wear the noise comes from.)
