There's actually a bunch of guys that do that at woodworking shows. They are trying to sell you bandsaw guide bearings. Sort of turns your bandsaw into a scrollsaw.
The one this guy did was probably the easiest, because it was large. I've seen them do the same deer, and the whole thing is only 2" tall. I suppose they did a larger one so the camera could see it. But from a bandsaw radius perspective, the tiny ones are more impressive.
