Vintage Engraving Collage — Style Prompt

A magazine collage made on a paper table: public-domain engravings, stamps, old photographs and printed ephemera are cut out with a white paper margin and laid over torn sheets of flat colour, and the pieces move like cut-out animation, on twos, with paper thickness and real shadows. Numbers are drawn as our own "data engravings": engraved lines that swell with the value. References (grammar only): Terry Gilliam's cut-out animation (hinged moves, pieces that pop out, the stepped rhythm); Saul Bass's paper title sequences (a shape that becomes the next shot); contemporary editorial collage (torn colour fields, halftone clippings, ransom letters, typewriter slips). Copy none of their characters, layouts, typefaces or music, and never name them in a film.

1. Essence, and what it is not

• Real printed matter, cut by hand. Every figure is a cut-out of a real public-domain print (an engraving, a stamp, a news photo, a line drawing), with a slightly rough white paper margin around it. Nothing is drawn in a vector or 3D way to look printed.
• Flat torn colour behind it. Large torn sheets of a few flat colours (teal sky, ochre disc, mustard sun, cream strips, paper clouds) make the space; their edges show a white fibre fringe.
• It is paper on a table. Every piece has a thickness (a 1–1.5 px cut edge), a shadow from a top-left light that grows softer and further as the piece lifts, and a paper back that shows when it turns over. The table is old paper, visible at the edges.
• Cut-out motion. Pieces slide in, overshoot and settle, drop and bounce, swing on a pin, turn over, get cut and scatter, stepped on twos. Nothing scales or rotates smoothly like software.
• Our own addition: the data engraving. Charts are engraved, not plotted: parallel lines whose width follows the value (the copperplate swelling line), cross-hatching at the peaks, a thin ochre wash, double-rule axes, torn breaks for broken scales.

Not Halftone Dossier (that one is a case file of documents; here the printed matter is cut free and performs), not Woodcut Print or Copperplate Engraving (we never re-engrave the whole frame; engravings arrive as found pieces), not Paper Pop-up Book (no 3D folds or depth stages), not a scrapbook slideshow (pieces move as puppets, the camera moves over a table).

2. Materials & rendering

• Cut-outs: a scan, a hand-traced or computed mask, the scan's grey turned into ink amount on a cream card, a white margin dilated around the mask with a slightly torn edge. Line art with a transparent ground gets its silhouette by closing and filling holes. Hand-colour (brass, mustard) only inside the cut, never as a gradient.
• Separated plates: a two-colour print (a poster, a label) is split into its ink plates by hue and re-inked in the palette; each plate can then be printed, shifted or turned on its own. Upscale before tightening the ink edge so lines stay crisp.
• Torn colour papers: flat colour with a faint mottle, the edge displaced by fractal noise, a thin white fibre fringe outside it.
• Old paper: a mottled cream base with fibres and faint foxing, lighter than a raw scan; it can be tiled with mirrored copies, so the table extends without seams.
• Halftone: any photograph enters as a 45° dot-screen news clipping on newsprint, torn edges, a typed caption.
• Paper physics in the composite: under each piece a cut-edge copy in a darker paper colour, offset down-right; two pre-blurred shadows mixed by height; the back side is paper colour with about 10 % of the mirrored ink showing through.
• Bake, then move: the heavy work (masks, separations, tearing, textures, engraving, halftone, typed slips) is baked once into sprites; the page only moves sprites. Grain is added in the mux, not drawn.

3. Colour logic

• A restrained palette of six: old paper, cream card, warm black ink, ochre red, teal, mustard. Large areas are paper and flat colour; heavy black is limited to engraved lines, small slips and silhouettes.
• A printed subject keeps its own inks, re-inked once into two tones close to the palette (for a two-colour poster: its red and its black), and only the subject uses them.
• One colour carries meaning per film beyond decoration (ochre for the data wash and one key figure, mustard for the slip that names it); flat colour papers are scenery.
• Example (our demo): paper #ECDFC2, card #F6EEDB, ink #221C17, ochre #C65F3A, teal #2F7F7A, mustard #E1AB3B; subject inks #C8463F and #2F5D8C; cut edge #B49D78, paper back #E9DFC8.

4. Type & subtitles

• All type is printed on its own slip of paper and placed like any other piece: no type floats on the frame, no outlines or drop shadows on letters, only the slip's shadow.
• Faces with a period feel, all OFL: an old-style serif (e.g. IM FELL English roman, italic and small caps) for titles and labels; a typewriter (e.g. Courier Prime) for slips, receipts and data; a CJK serif (e.g. Noto Serif SC, subset) for Chinese.
• Ransom letters for a hero word or number: one slip per character, rotating fonts, papers and inks, slapped in one per eighth note. Old-style serifs have old-style figures (1 like I, 0 like o): digits come from a lining face.
• Typewriter slips type out letter by letter on a blank slip (monospace advance), with a key sound per letter.
• On screen: Chinese ≥ 34 px, English labels ≥ 24 px, data numbers large enough to read at the widest framing they appear in.
• Subtitles (when there is a voice): two slips stacked at the bottom left, a black newsprint slip with the Chinese line (about 40 px) over a cream typewriter slip with the English line (about 30 px) typing out. One line per language, split long lines into two cues. Keep that corner (about 1100 × 180 px) free of anything the viewer must see.
• Comparisons and verdicts: every compared item fully in frame and held ≥ 2.5 s.

5. Motion quality

• On twos (12 drawings a second) for every paper piece; the camera moves smoothly every frame.
• Slide in from off-frame with a small overshoot and a 2–3 drawing side-to-side settle; drops accelerate and bounce once; a slap arrives in two drawings (a slightly larger copy high above, then down).
• Moving pieces carry a hand jitter (≈ 0.7 px, 0.25° per drawing); resting pieces are still.
• Hinges turn around a pin and overshoot; a sheet can turn 180° flat on the table.
• Flips around the vertical axis show the paper back and a wider cut edge mid-turn.
• State changes are substitutions, not morphs: swap in a new cut-out (an open lid for a closed one, a printed sheet for a blank one).
• Never a smooth software scale, never transparency fades between pieces.

6. Camera grammar

A rostrum camera over a paper table: 2D only, but it can push, pull, pan, rise and tilt across a table much larger than the frame.

• Wide establishing on the assembled collage; follow a moving piece; push to read a detail; pull back for scale.
• Through a shape: push into a hole in the paper (an oval frame, a window, an empty album slot) and the next scene is already inside it.
• Whip pan sideways along the table, a paper seam between the two scenes.
• Match cuts on the same piece at a new size; match on action (a piece leaves the top of frame, enters the next shot from below).
• Rise along a growing data engraving, then pull back so the whole comparison is in frame.
• Keep the view on the paper: zoom ≥ 1 on a single-sheet table, or tile the table for wide pulls.

7. Sound palette

• Paper foley for every piece: slides (band-passed noise with fibre grain), pats when a piece lands, slaps for type, flutter for flips and wings, scissors snips, typewriter keys and the carriage bell, a rubbing roller, the scrape of a growing chart.
• Score from small-ensemble period instruments: tuba and bassoon staccato, pizzicato strings, clarinet, xylophone, glockenspiel, harp, woodblock, timpani; a march or music-hall oom-pah, with a minor turn where the story turns. No generic piano and strings.
• One near-silence before the turn, and transitions carried by sound (a whoosh through a shape, a whip).
• With a voice: compress it and set it about 10 dB over the music; duck the music's 300 Hz–4 kHz band while it speaks.

8. Native moves

• Cut it out: a found print enters as a cut-out with its white margin; it can be cut again on screen with scissors and scatter.
• Assemble: torn colour papers and cut-outs slide in one by one and build the scene or the subject.
• Turn the sheet: a whole sheet or piece turns 180° flat on the table, or flips to show its back.
• Through the hole: the camera enters a shape cut in the paper into the next scene.
• Ransom and typewriter: words arrive letter by letter as slapped clippings or typed slips.
• Data engraving: a value grows as engraved lines, the camera rises with it, a torn break marks a broken scale.

Our demo opens on assemble with ransom letters, uses turn the sheet as its turn and ends through the hole back into the first scene. A new film opens and ends another way: a single cut-out falling into frame and landing with a thud, a typewriter slip typing the first line before anything else appears, an ending on a last stamp or seal pressed onto the collage, or a rise until the whole table reads as one poster.

9. Pitfalls of the medium

• A cut-out without a margin or shadow reads as a digital sticker; one with a fat, even margin reads as a sticker too. Keep the margin thin and slightly torn.
• Shadows from different light directions, or shadows that do not change with height, flatten the table.
• Smooth scaling, fades and easing curves that never overshoot read as software, not paper.
• Too many pieces: one subject per frame, about twenty flying pieces at most, leave the bottom-left free for subtitles.
• Upscaled scans go soft and blotchy: separate and tighten the ink, use the largest public-domain scan, and keep cut-outs at or below their source size where possible.
• Old-style serif figures in numbers, letters with outlines or glows, system fonts.
• Copyrighted or "no known restrictions" images: only public domain and CC0 prints, each one in the credits.

10. Engine

• Python (numpy, scipy, Pillow) bakes the parts into parts/*.png and parts/manifest.json: paper and torn papers (demo/src/bake.py), cut-outs, separations, halftone, slips, subtitles, data engraving (demo/src/bake2.py, helpers in demo/src/collage_lib.py, the tone-to-line engrave() among them).
• The page (demo/index.html, Canvas 2D) loads the sprites, derives each piece's cut edge, two shadows and paper back at load, and draws render(t): keyframed poses on twos with overshoot, settle and jitter, scenes with their own cameras, transitions by clipping one scene inside a shape of another.
• Foley and score come from the page's events (window.EV) in demo/mix.py.

11. Variation space

The agent decides the printed matter, the story, which pieces move, where the camera goes, the data that gets engraved, the words, the pacing and the score.

• Three structures: an object's history told by the objects themselves (a ticket, a map, a letter); a portrait assembled from the clippings of one life; a social or psychological idea taken apart into its printed symbols, then put back together.
• Three openings: an empty paper table that fills one torn sheet at a time; a single cut-out falling into frame and landing with a thud; a typewriter slip typing the first line before anything else appears.
• Three endings: the camera passes through a hole back into the first scene; a last stamp or seal pressed onto the collage; the camera rises until the whole table reads as one poster.
