Very cool! Would be great to be able to rotate/zoom the 3D space.

Not only can you rotate with right-click, you can also pan and zoom and manually add cells.

Huh, somehow it didn't work for me the first time (chrome, macos), but now it works.

Am able to rotate/pan/zoom with firefox on desktop using the mouse buttons and scroll wheel

It can at least be rotated, as I did so.
