That is very cool. I remember seeing a post on this and there was a line of thinking to the tune of "modern engineers are no where near as impressive as the ones 50 years ago". Someone woking in astronautical engineering asking a basic question about how this would handle things like eccentricity, procession of nodes, etc, and the response was simple: "it doesn't!". Honestly these things are really cool I would totally go for a trackball globe being spun around by some Arduino controlled rollers. Even without the gears a modern recreation would be a really cool thing.
