I think the gist of this suggestion is that while a scarf works as a hair, the hat would be a lot better as a 3d object, given that it could be textured and essentially be less shit looking.
It was one of the first things in it's class, and it was a great idea, but we have much better tools now. A re release of something like this where we have the hat and the scarf as separate things (3d obj and hair respectively) could be kinda neat. Updating it based on the tools we now have available.
