If you create something worth seeing with it show to me, I am curious :D

This is a quick demonstration of my autorigger I wrote for the variable forward kinematic concept presented by Jeff Brodsky in this video: vimeo.com/72424469
This is my first maya scripting project of this size but since it would require a lot of manual steps to set this up all by hand I decided to write it as an autorigger right the beginning plus I thought it could be fun. It is the first time I used pymel and made an UI for a maya script so the code is probably pretty messy but it reliably does what it's suppossed to do.

Variable FK is a bit more dynamic than normal FK controls because it adds the feature to move the controls along their jointchain while the influence of a control on a joint is determined by the distance between them. The moving along the joints part works similar to a ribbon rig and the distance-influence calculation is achieved with utility nodes.

This kind of rig works well for:
- tentacles
- tails
- plants (mainly ferns)
- belts
- adventure time style limbs
- elephant trunks

and probably much more. feel free to experiment, feedback appreciated
