The impressive part is the entire system is mechanically timed and synced without using any computer control. Also, that little motor is running the entire machine. Still the best toy ever made in my opinion. Been into technic sets since the 80's.

This is one of my favorite videos of his. https://www.youtube.com/watch?v=oYhAKxOlfXQ All movement and actuation is powered by a single motor. The timing is synchronized through gearing and linkages. I am in awe whenever I watch it.

This is kind of like playing a Zachtronics game without using the sync instruction (I think each one has a "wait for signal" concept), but in real life!
