In that one song that I forgot the name of it supposedly scrolls through all the possible combinations of 6 letter like it's some base 26 counting system. The thing is that I inspected it came by frame and say that there was the word memory separating huge chunks of the combinations. Are those there to save memory or for some other reason?
to save memory and time in multiple ways. give it a try: try displaying all combinations of 6 letters in alphabetical order. try to do anything with it. try to save it in a file. try to send it to someone. try to depict its entirety on a screen in any way, in any reasonable amount of time and/or at a reasonable frame rate. i think you may be surprised at how astronomically large a quantity we're dealing with
