Plaster restoration is also amazing to watch. A lot of crown molding isn't wood, but plaster. It's thrown into the corner where the wall meets the ceiling, then some guy with a more apparent skill in his arm than a major-league pitcher takes a trowel that shapes the plaster into a "carved wood" shape at the same speed a normal mortal would use to draw a line with a Sharpie.
I still don't get how those guys could make whole walls and ceilings flat using only a wet plank of wood with a handle on it, but they can.
