Pinch to zoom on a macbook makes the entire map sweep across the globe. Makes it very hard to use even if it's a neat idea.

Happens on desktop with Firefox as well.

Looks like a bug with the view origin point being mis-matched with what the view's actually focused on - maybe high-DPI scale mis-match?

Sounding like desktop/laptop with a mouse is the only way to interact with this site. It's a great first try though. I spent a few minutes poking around for sure.
