Using the simple granular synth packaged with Pluggo I created this nasty tearing sound. Towards the middle it sounds like it’s causing speaker damage, but don’t worry your speakers are safe. The original waveform was a sawtooth before the grain table algorithms manipulated it as you can see in the image.

Granular synthesis involves separating a waveform into grains that can be rearranged either randomly or with various formulas resulting in dense or scattered clouds of sound particles. For more information about granular synthesis, check out this entry on Wikipedia.
