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 😊

people thinking about upgrading to the bigger AI subscriptions:
check your model use first, make sure you're using appropriate models for the appropriate tasks
i.e. don't let Opus 4.5 summarize or format text, make its smaller brothers do that

there are a lot of PNG -> SVG converter tools, but they all suck
Adobe, canva, freeconvert, and more have issues with anything that is a little more complex then an icon. Note the squiggly lines 👇
convertio . co was spot on - if you need an SVG conversion, go there 😊

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
