How to create white noise: generate a random number. Then do it again, until you have enough numbers. That’s pretty much it.

Flip a coin, roll a die, or pick a number between zero and 250 pixels like the generator above is doing. Each number is completely unrelated to the numbers before and after it, leading to a result that jerks around unpredictably, hitting loud spikes and quiet lulls chaotically.

I coded this visualization of the noise functions in Processing, a fun and surprisingly powerful graphics-and-art-oriented language/programming environment.
