Pixel sorter effect - without plugin

Trying to recreate what's possible to achieve with the famous "Pixel sorter" plugin for After Effects (http://aescripts.com/ae-pixel-sorter/), but... without the plugin !

I've come up with an interesting result, with a bunch of native AfterEffects' effects like CC Ball Action or Minimax, customizable with expression controls (sliders, checkbox for the direction, randomness, threshold...)

If enough people look interested in, I could probably post it as a free preset on our Motion Cafe website !
