How to create an alias for an object's properties? I'm curious if anyone knows how to rename an object's properties?  For example, can I rename head.rx to be head.nod? 

In maya, there is an aliasAttr command that does this.

Would love to do it in blender, too. :)

cheers!

You can't rename an object's properties, but you could extend it via its RNA, or add a custom ID.  IIRC, you can then add a driver to the original property, so head.nod ->> head.rx.  See here:

That said, if animation channel usability is what you're after (judging by the names of your example) you might be better off just making a bone called 'nod' and then driving whichever axis is going to rotate that head downwards.  

Not as extensible as Maya, for sure!
