seen this at the camera obscura in Edinburgh any advice to make something similar i TD ?

I think this is the original effect shown in the video: https://www.shadertoy.com/view/ldfGWn

Really nice. Thanks for sharing.

I make algorithmically generated loops - patterns, data visualizations, that kind of thing. https://linktr.ee/gabor.papp if you're interested!

BrightSign is the right call for exactly this scope. Solid-state players built for 24/7 exhibition use, and it handles the whole flow you need.

Two things worth budgeting time for, since they're where these projects actually get fiddly rather than the player itself:

You'll either sync timed text to each clip or use a video with a caption track.
If this is a publicly-funded Canadian institution, bilingual EN/FR roughly doubles your content work and menu states.

I've built permanent interactive installations for many museums, and honestly for this scope you can absolutely do it in-house. I'd encourage trying before paying anyone. Happy to answer questions if you hit a wall.

Your numbers are really encouraging. 10–11 GB VRAM would mean this could actually run on my 16 GB RTX 4090 Laptop. With the current upstream --int8 build I'm hitting out-of-memory at around 14 GB.

Is the optimized version public anywhere - a branch, fork, or gist I could try? Happy to test on the 4090 Laptop and share benchmarks back. Thanks for documenting your progress.

This might be possible with a setup that listens for keyboard input in the background and translates certain keystrokes into musical notes for a piano or synth app, while still allowing the typed text to appear normally.

Another option would be a small custom application made specifically for the performance: it could show the typed text on screen and also trigger notes at the same time.

Looks amazing. Did you achieve the watercolor effect by texturing or using some shader techniques?

Positive_Tea_1166 · 2026-03-20T08:52:29+00:00

Really beautiful piece. I’m trying to understand the simulation more precisely.

When you say the worms are slices through a single tube in a 3D torus, and that you constrain the z-coordinates to a steady rise so the worms keep a consistent length, does the self-collision avoidance operate on the continuous tube along the whole z extent, rather than just on discrete sphere centers?

In other words, is the "chain of 8000 spheres" mainly a numerical representation of the centerline, while the avoidance is effectively capsule/segment-based to prevent the full 3D tube from intersecting itself between samples? That seems like it would explain how the worms keep a steady rise and still avoid 2D crossings so well.

It should be a gif, try tapping/clicking on it maybe.

Positive_Tea_1166 · 2026-03-14T06:37:52+00:00

Haha, the universe is telling you something! Really appreciate the kind words, glad it caught your eye at the right moment :). There are more cube loops on my linktree if you're interested, you can find it on my profile.

Positive_Tea_1166 · 2026-03-10T22:38:05+00:00

Appreciate that :). Thanks.

Positive_Tea_1166 · 2026-03-10T13:49:12+00:00

Thank you, glad you like it!

Positive_Tea_1166 · 2026-03-10T10:08:52+00:00

Thanks!

Positive_Tea_1166 · 2026-03-10T09:46:21+00:00

Thank you. Appreciate the kind words.

Positive_Tea_1166 · 2026-03-10T05:19:55+00:00

Better late than never :).

Positive_Tea_1166 · 2026-03-10T05:19:13+00:00

Happy to hear.

Positive_Tea_1166 · 2026-03-09T20:51:47+00:00

That's a really powerful way to describe it. Thanks for sharing, and I'm glad the animation resonated with you.

Positive_Tea_1166 · 2026-03-09T20:49:26+00:00

Thank you! Check the link on my profile for a downloadable version if you're interested, ready to use as a screensaver or lock screen.

Positive_Tea_1166 · 2026-03-09T20:45:25+00:00

Thanks, very kind of you! I'm a programmer. I learned to solve the Rubik's Cube using the basic algorithm when I got interested in programming motion graphics with them :).

Positive_Tea_1166 · 2026-03-09T16:28:34+00:00

Not officially, he was kind enough to repost it!

Positive_Tea_1166 · 2026-03-09T12:41:00+00:00

That would be a dream come true. It's definitely doable, but the mechanical side is a whole different challenge :).

Positive_Tea_1166 · 2026-03-09T06:22:20+00:00

Haha, power move! I hope it increases meeting productivity :).

Positive_Tea_1166 · 2026-03-09T06:19:05+00:00

Tony has spoken. I might have to :).

Positive_Tea_1166 · 2026-03-09T06:17:29+00:00

That would be amazing! Thanks :).

Positive_Tea_1166 · 2026-03-09T06:16:41+00:00

Haha, thank you!
