Bytebeat was invented by Viznut of PWP fame in September of 2011.  The core concept is applying an algorithm to t where t equals the number of steps in time based on the chosen sample rate.  The output is 8-bit and values above 255 are wrapped.  Because of the nature of this format it may be quite difficult to generate something both pleasant and unique.  ;)
