YouTube served me up a video from this creator where he went over the trailer-to-functioning-ride setup of a mobile Gravitron ride. He's got a variety of 'em on this channel, well-narrated and a fascinating look into what's involved with these machines.
Real good brain candy!

6 years ago, I wrote an AES AEAD library in Dart just to go through the motions and learn the encryption. I had CCM and OCB, but never added GCM... Gemini 3 and Antigravity said "hold my beer". NIST and boringssl test vectors passed!
