it's a simple Newtonian n-body sim. You can drag emojis into orbit around the Sun, switch to an Earth/Moon view to see lunar orbit up close, or throw things into a black hole

what's the most ridiculous "stable" orbit you can get?

I was explaining orbital dynamics to someone today (at a very basic level) and realized it would be way easier to just show it.

so we built this little gravity sandbox in about 30 minutes with Claude (link below) 👀

it's really fun to try and get a stable orbit 😊

it might seem obvious, it might not, but make sure your checkout flow is seamless

need the user to login first? remember what they were doing and automatically continue it, once they're logged in

new account? same deal, continue automatically after they've registered
