I discovered a fun online game today (through the kisrael.com blog) that is about designing machines to move an object to the target zone. Looking at the forum, I’m amazed at the things people have “built” to solve the puzzles. You can see one of my solutions to a puzzle below.
I’m not an engineer so I build by trial and error, but it’s still fun to see the machines fail (often amusingly), and even better when it works.
