At the Exploratorium, there was an exhibit titled "Giant Ball Bearing," and all a person was supposed to do at the exhibit was turn it and feel the workings. Words in the middle of the bearing read, "Some machines just feel nice," and after turning that bearing around and around many, many times, I have to agree. Sometimes there is a visceral pleasure in interacting with machinery -- Apple has stressed that notion in their design -- and after watching the video below, I now feel certain that there is also an aesthetic pleasure in watching machinery. Let me know what you think.
