    this isn't the one I was talking about but its all I could find, this is truly random:


    We use 'Quantum Random Bit Generator' (QRBG121), which is a fast non-deterministic random bit (number) generator whose randomness relies on intrinsic randomness of the quantum physical process of photonic emission in semiconductors and subsequent detection by photoelectric effect. In this process photons are detected at random, one by one independently of each other. Timing information of detected photons is used to generate random binary digits - bits. The unique feature of this method is that it uses only one photon detector to produce both zeros and ones which results in a very small bias and high immunity to components variation and aging. Furthermore, detection of individual photons is made by a photomultiplier (PMT). Compared to solid state photon detectors the PMT's have drastically superior signal to noise performance and much lower probability of appearing of afterpulses which could be a source of unwanted correlations.
