True randomness : But do try to create a login

True randomness is impossible to generate with finite state machines, so scientists at the Rudjer Boskovic Institute, Laboratory of Stochastic Signals and Process Research, came up with a true we-based random number generator. QRBG is a fast, nondeterministic and novel random number generator whose randomness relies on intrinsic randomness of the quantum physical process of photonic emission in semiconductors and subsequent detection by the photo-electric effect.
But if all this is kind of boring, visit the site and try creating a login in the site. You'll find the security question that verifies whether you are a human or a bot interesting. Try it.
