From the comments – Ned shows us this very excellent video of “Del’s Beautiful New Wooden Machine”, and beautiful it is!

An intricate hand-cranked machine made entirely of wood and glue (no metal or other materials). It was designed and built by my friend Del, using many different woods and incorporating a variety of mechanical motions. He has made several other wooden machines, but calls this latest one his crowning achievement.

It’s another awesome machine built only for the love of machine-making itself. I’m starting to think think there must be a whole a genre for these devices! Hmmm … come to think of it, I do believe there’s already a name for this type of thing — “art”
