cool! I'll take a look one day I want to be able to code stuff too, hopefully in fabric engine.
https://drive.google.com/folderview?id=0B_9lezVBprmDdEZtdUNzUmpVYjA&usp=sharing here's my rig I used to animate flybys and stuff with a normal cam. used to take so long till I made this rig (prior to this vertigo effect) I also made a standalone one in AE. it's based on zxy rotation order so the gimbal slider is for when rotX is +-90degs vertigo is just that, vertigo effect / dolly-zoom effect fov is the horizontal fov so it works with the thomas volkmann softimage to after effects python script too now I gotta figure out how to make it in maya. could be a while.
