Hi, David Tristram here. founding member of Raster Masters, 1990's computer graphics performance ensemble. As @hopkins has mentioned, we used high end Silicon Graphics workstations to create synthetic imagery to accompany live music, including notably the Grateful Dead, Herbie Hancock, and Graham Nash. After many iterations I'm currently working mainly in 2D video processing environments, Resolume Avenue and TouchDes…

I think I saw some of your work at a few Dead shows in ~1992

Is there anything which supports music input? I liked Winamp era visualizers, but the art seems to be dead today.

I've been working on an free open-source macOS app for just that - https://nottawa.app Hoping to release in the next couple months! The UI has been greatly improved since I took the original demo on the site, the real thing is MUCH better now.

May I ask where are the sources? Looks great, any plans for Windows or Linux (Docker) version?

I used to spend so much time messing around with MilkDrop in Winamp. You could grab existing visualizations and see what they were doing, and make your own edits. Thanks for the nostalgia hit!

MilkDrop 3 latest release was in 2023!

Thank you, that's exactly what I'm looking for.

Really interesting! I'm very much interested in pychedelic graphics. I played around with shadertoy a little bit maybe I should give it another go. For anyone interested I made some cool visuals by interpolating prompts in stable diffusion 1.5 like https://m.youtube.com/watch?v=ajfMlJuDswc. I found that the older diffusion models are better for abstract graphics as it looks more "raw" and creative.

If anyone wants to play around with psychedelic graphics without going too low-level, [hydra]( https://hydra.ojack.xyz/ ) is a cool javascript based livecoding environment with a gentle learning curve.

You can do that easily with https://ossia.io :)

Who were the other people in Raster Masters, and what crazy stories from Grateful Dead concerts can you tell? ;) Every time I've ever plugged in a modern projector into a laptop at a presentation it's so stressful, like rolling the dice if the screen will ever come up. What kind of a projector and calibration and preparation did it take to project live hires SGI video onto the screen above the band?

I would guess either https://en.wikipedia.org/wiki/Eidophor or https://en.wikipedia.org/wiki/Talaria_projector https://www.ebay.com/itm/225229726689

Sure! It should have been linked on the site, that’s totally my oversight.

https://github.com/joenot443/dude_wake_up

The code isn’t anything to write home about, it’s in C++ leveraging OpenFrameworks and OpenGL. I’m an iOS and macOS dev, but after the initial release I’ll get started on porting to Windows and Linux. OF generally works well multi-platform so I’m hoping it won’t be too hairy.

I’m specifically targeting the non-technical artist/creator market, ideally with optional macOS App Store distribution. I’ve been involved in the live visuals scene in NYC a bit and something I commonly heard was that musicians and DJs wanted visual accompaniment which just works out of the box. TouchDesigner etc are incredibly powerful, but generally out of reach for non technical folks.

I’ve contracted a great artist from UpWork who’s been making presets which will be included. There should ideally be as little friction as possible for a user to go from first launch to live, audio-reactive visuals.

Thanks for checking it out! :)

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.

The trick is go out of body. Eyes closed and let your mind create all the visuals. Then its like being in alex grey land

True, more interesting things happen when you close your eyes.

Hydra actually works well with music input! It grabs audio from the mic and `a.show()` will show you the frequency bins. Then any numerical parameter can be modulated by the intensity of a bin, for example: `noise().thresh(()=>a.fft[0]*2).out()`

> It grabs audio from the mic

Is it possible to grab from default audio output device instead of mic? Probably not as it's browser based. I suppose mic can be faked on OS level somehow.
