AE Fish Rigging Test

A quick test done entirely with AfterEffects (and with no keyframe at all !), with the help of the awesome new "Bezier IK" from DUIK script (http://duduf.net/?page_id=11) and basic expressions, to rig a 2D koi fish seen from a top view.
The water is just done with a bunch of fractal noise and dispersion effects.
