A typical use case for an observer of the logged project.

I've been wandering Maker Faire all day, especially interested in someone that's used those strange small bearings. You know the ones, right? Hey, my Build Logger app just buzzed my phone. There's a project nearby that actually uses them! Tap. Ah, I see the pictures. It looks so easy. There must be more.

"Hi there! I see you used the mark 7 bearings. How'd you mount them so level?"

"I'm glad you asked. Command record."
