A new means I had not head of, how random, repeatable is the result?
Scientists Use Crystals to Generate Random Numbers

Computer scientists at the University of Glasgow in the U.K. have generated random numbers through an automated system that completes inorganic chemical reactions and grows crystals within a computer numerical control machine. The researchers outfitted a camera to the device to record images of the solidifying crystals, then used image-segmentation algorithms to examine the pixels corresponding to the crystals; a binarization algorithm converted the data into a series of 0s and 1s based on the crystalline geometry, repeating the process until the desired binary-code length for encryption was realized. Comparing this random-number generator with the Mersenne Twister pseudorandom number generator, the researchers found the new system decrypted messages faster. ... "
