afterEffects Expression Controls

This will be a new living document, mainly so I can keep up with my AE expression controls. I'm no coder but these expressions are extremely handy.

Opacity: x + time Opacity scales w/timeline, x being starting opacity between 1-100
Wiggle: Wiggle(.5,100) Randomizes any property (rate per sec, max unit of change)
Loop: loopOut("cycle",1); Loops a subcomp or footage file, great for BG builds
Noise: NoiseMaker; good tutorial on making grid patterns with random behaviors
