Change “random(0)” to “random(time(0))” so the videos are less easily removed by a bot. time(0) is the number of seconds from January 1, 1970 at midnight, so the random seed keeps changing. It’s still be black and white noise but not the same noise as anyone else.

You can change that “225”, which is actually 255 in the tweet, to any number smaller than that, but it’ll make the noise darker and reduce the randomness of it. The result still has to be between 0 and 255, so you could change it to 12+random(time(0))*243 or something like that if you really wanted to make it no darker than 12.
