Ella is a cartoony bipedal rig who is free to download and use. I'm not too fussy about what's done with her, but please don't re-upload elsewhere and sell it... If you end up doing some slick animation for her, I'd love to see it! And if you have any problems with the rig, feel free to drop me a line at my email and I'll see what I can do.

The bridge is a prop rig I developed in 2014 as part of a Rigging Dojo course. Feel free to whatever you please with it! Bear in mind that the rig is stable only in the 2015 release of Maya.
The drinkbot is a prop rig I developed in 2014 as part of a Rigging Dojo course. No restrictions on use.
