Long time no see! Here to advertise that BlueSky recently added video support, so if you've migrated over there and are missing your daily dose of random three-body problem videos you can now see them here: bsky.app/profile/threebodybo…

While the bot can no longer post to Twitter, it made a great simulation today -- the full version is on the YouTube channel here: youtu.be/uHDV4r35twk

Ironically this tweet has had no problem summoning lots of problematic bots…while this account is one of the “good” ones that was supposed to be left unscathed by recent rule changes.

The bot is broken once again, because Twitter has randomly suspended (no reason/notice given) my “app” that I use to authenticate/post the simulations. I tried to submit a support ticket and they just sent me a password reset link… Paging @TwitterSupport @TwitterDev for help!
