Pointy's eyebrow rig has been annoying me, so I redid it in the new Bendy Bones. It is so much nicer now. Here's a video with my prototype rig. Enjoy! :)
Bendy Bones was created by Joshua 'Algorith' Leung and Daniel Martinez Lara (director of the Goya-winning short "Alike"). It'll be available in nightly Blender builds on https://builder.blender.org/download/ and will be part of Blender 2.78 when it's released later in the year.
