Risograph film of a starling murmuration
A 70-second square risograph-print film of one evening's starling murmuration over a marsh, from sunset to roost, drawn in Canvas with a string score. Opus 5.5 chose the subject from a three-sentence free-range prompt, inside a repo of riso skills and docs.
“prompt was simple since the project (repo) had the docs and examples already”
Lets make a ~70s riso film of your own choosing, free range. The project docs here for this session are for support and examples, but you're not required to follow them. Find and use free instrument sound effects when making the score for this film
Make it yours. Change "~70s" for your length. Keep "of your own choosing, free range" to let the agent pick the subject, or replace it with one of yours, and change "free instrument sound effects" for a different kind of score.

How it was made
Run inside the creator's riso-windowseat repo. Its README says that making the first film, Window Seat, and two shorts before it produced a reusable kit of Claude Code skills (riso-film, riso-score, riso-still), craft docs, and a render harness, and that Roost was made with it next. The post doesn't name the film, but it matches the repo's Roost: 70 seconds, 1080 × 1080, a starling murmuration from sunset to roost, scored for strings. Roost's notes say each starling is a 2 to 3 px ink dot on an analytic flock sheet rather than a simulation, and the score uses CC0 string recordings from VSCO 2 Community Edition embedded in the HTML file, as the prompt's request for free instrument sounds allowed.

Look notesby Reference
A risograph print of a marsh at dusk seen from one fixed spot: a low sun over still water framed by reeds, a flock of starlings in a dark halftone cloud above it, and the sky cooling from gold to night blue.
- Color
- Golden orange and yellow sunset over a pale gray-green sky, then lilac and periwinkle dusk and deep night blue, with indigo reeds and birds, a visible halftone grain, and slight color misregistration.
- Type
- None in the sampled frames.
- Framing
- Square frame with reed silhouettes on both sides and along the bottom, a far shoreline across the middle, and the flock above it with its reflection in the water. One frame looks straight up into a sky full of individual birds.
- Structure
- The empty marsh at sunset, small groups gathered over the sun, the flock bent into a dark ribbon, the flock in changing shapes against the afterglow with a falcon speck nearby, a close pass of birds overhead, the flock low over the far reeds at dusk, then the empty water under the first stars.
