As I already mentioned in my first post, I wanted to create a Space Billiard game related to the Hitchhiker's Guide. That means n-body calculations, collision, path anticipation, etc. that's not included in typical game engines, let alone in HTML ones. Progress has been slower as anticipated, I don't really have a game here, but some technology prototype that already starts to make fun (well, mostly because of the typical weirdness of non-polished sandboxes...)...

The browser has to do some heavly lifting, calculating 10 or more n-body gravitational effects for a 1000 timesteps, 60 times a second... :blush: I'm astonished, that this actually works...
