An interesting read from Phil Taylor, one of the key guys behind CAT, ICE and now Fabric. He's gone from building an entire rigging system within a program, then building an entire node network system within a program to building an entire program to support a whole new rigging system. He doesn't lack for ambition.

A character TD from Image Metrics talks about various philosophies of facial rigging. He details the common mistakes seen in facial rigs, how they implement their solution while also working within the constraints of game engines and answers various questions posted by people watching online at the time of recording.

Pretty old now but some nice cartoony rigging demos.
