Fun thing: in relativity u,v are typical variable names used for a really funky coordinate transformation that mixes space and time, sometimes called Penrose coordinates [1]. So when I saw this:

> uv.x = uv.x + sin(time + uv.x * 50.0) * 0.01;

> uv.y = uv.y + sin(time + uv.y * 50.0) * 0.01;

I thought, wow, what on Earth is going on here? But no, it turns out that its not that psychedelic. They could have used p,q or any other variable pair but its still quite interesting geometrically [2].

If this is your kind of thing and you ever get a chance to see the musical artist Tipper alongside Fractaled Visions driving the visuals, you’re in for a treat. Most spot on visual depictions of psychedelic artifacts I’ve witnessed. Saw them together last year and it’s the no. 1 artistic experience of my life. The richness, and complexity of Fractaled Vision’s visuals are almost unbelievable. Even knowing a lot about…

ooo I was there

This might have been written just for me, I love the premise. I am truly fascinated by people who attempt to reproduce the actual physiological vision effects of psychedelic drugs. Psychoactive drugs can be probes into the inner workings of our minds - in some scientific sense - and exploring the vision effects seems likely to suggest interesting things about how our visual system works. Mostly, I am just impressed w…

This is 100% not what psychedelics look like. It's generally just mildly more saturated colours and the feeling that everything is possibly breathing or swaying in a more natural way. I dunno what happens if you take insane amounts tbf. I always thought that psychedelic art was a bit more about the sort of thing that is super appealing to look at while tripping.

a bit of a tangent but I'm surprised how heavily visualisers and the like always seem to focus on packing in as much colour as possible. With OLED screens it feels like there's a ton of potential for making really great black-heavy ambient visuals that so an idle TV can become a feature of a room's decor rather than just a big black rectangle in the middle of it.

Early 90s, Todd Rundgren realized a Mac App called Flowfazer - it didn’t simulate your experience but was helpful as a distraction to move you along. Some people used it to provide guidance for their own creations.[2]

It was a time of screensavers and palette animation.

Yeah, I have an older LG and it has a disappointingly simple 4k fireworks visualization when it "sleeps" that always makes me wish I could create a custom replacement.
