Cranky Franky: lol ... completely digital of course :)

when a computer 'calculates' a random number it looks up a value in a very fluctuating function

when you dont seed the random call it will take the first value from that function .. and the second value on its second call .. that why unseeded calls always produce the same series

most language allow you to perform a seed with the clock of the processor which will then place you into an area of the function where you havent been before and there a new series will be produced .. but still its a series with some periodic repitition
