I honestly have no idea how intensive it would be to have head textures that allow for short .gif loops but how possible would this be to achieve? I would love to see people with heads that can show some emotion or movement (i.e. winking / smiling / snarling) even if its only 2 or 3 frames worth.

If this is totally not even worth the time I understand I just figured I'd ask the question ¯\_(ツ)_/¯
