VR in this is gonna make me hurl.
I felt kinda nauseous just watching the video!
It’s hard to find a comparison for what this effect feels like, but I think the closest sensation I can come up with is like when you’re on a roller-coaster that flips you upside-down, so you have a view along the ground, but with your feet up in the air… ulghh

Cool. Now do Nil, Sol and SL(2,R).

I’m guessing Escher intuited all of this.

Are you fenced in or fenced out is a pretty deep question that can be asked about many things in your life

Note: The free-flight can tax an older machine with thermal throttling, DPC latency or slow wi-fi issues. This Nil geometry fly around of the Earth in space seems to run smoothest.

Very nice. I’m not surprised that Henry Segerman is involved; he’s done a lot of visualization/outreach stuff in geometry in the last few years.

I’ll have to track it down, but I remember reading an Isaac Asimov essay as a kid where he described the view from various planets and I think it was Venus’ thick atmosphere creating intense light refraction that caused him to postulate a similar effect as seen in this video. Fantastic to see this demo, but alas, the Venera probes didn’t show the described effect.

It’s not strange, it’s wonderful.
Thanks. Absolutely loved Bill Plimptons stuff and had forgotten about it. Now will go back there!
May I suggest this is so much hyperbole
