Random.org offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. Built in 1998 and operated by Mads Haahr of the School of Computer Science and Statistics at Trinity College, Dublin in Ireland, to date 1,116 billion random bits have been generated for the Internet community. Many free services! http://www.random.org/ #Random_Numbers
Prime numbers; Random Walk by Daniel Becker: "The project consists of 14 double-sided A2 posters contained in a transparent plastic sleeve. Ten sheets explain the phenomena of randomness in mathematics and physics - four focus on all-day randomness and the quality of pseudo random number generators. Without title or specific order the sleeve contains the folded sheets at random like a pack of cards."
noiseSeedsame code, different noiseSeed each time.noiseSeed(); sets the seed value for noise(). By default, noise() produces different results each time the program is run. Set the seed parameter to a constant to return the same pseudo-random numbers each time the software is run.(code)
