We used a similar machine to peal apples in my home ec class in Western NY.
The orange peeler is one skilled guy! Reminds me of the green mango seller in Boracay. With a knife in her left hand, and the green mango in her right hand, a few twists of the mango and its peeled from top to bottom! Incredible! And you're right. It is a joy to watch such simple motions up close. You won't find similar joy in watching your kitchen peeler.
