Have you seen this video? It is amazing! This artist is remarkable. He loves music and making things. The whole idea for this came to him when he saw a computer program that calculates and prints a pattern to cut out wooden gears. Crazy.
My favorite part of the how-to video is how he says often that he made mistakes, but he just kept trying again. I’ve been showing the videos to the school-age children and have been trying to hammer that home: you will make mistakes and that is ok. Keep going.
