Holy smokes, how did I miss this? This is very lovely; a simple but surprisingly-useful kind of model, and perfect for a variety of uses (Faceless One, Void, Old One, Naga/octopus).
It makes me wonder why we don't see more usage of "sprite" like in Cyclone, and in more interesting ways like this. I think one could make a decent variety of "disabling" abilities that, while functionally similar, would look drastically different (based off of different custom animated models).
