There is a website called jsfxr (sfxr.me). It is used to generate sound effects for old-fashion games. It has power-ups and laser guns and stuff. There is a feature called “mutate” which changes the sound a bit. If you spam click the mutate button, a bunch of variations of the sound will play over each other. This makes some very creepy sound effects.
I just thought this was cool as the developer didn’t intend for the website to be used that way.
