TITLE
Spore Print — A Two-Colour Zine

PROMPT
A risograph-printed zine about looking for mushrooms, reproduced as a web page that behaves like cheap, beautiful two-colour printing. Invented publication: "SPORE PRINT, issue 3: The Wet Month", from an invented small press, "Damp Hands Press". Concept: the print process is the star: two spot inks, visible grain, slightly misregistered plates, overprint making a third colour.

Palette (strict two inks on paper): paper warm off-white #F4EFE2 with recycled-stock flecks and fibres; fluorescent pink #FF48B0; teal #00838A; where they overlap, multiply blending yields a deep violet-indigo ink (in the region of #3B2F5C, darker where both inks are solid). No black anywhere: all text is teal or pink, shadows are violet-tinted. Light page; the spreads lie on a pale cutting-mat grid.

Print simulation: every illustration is built as two separate SVG layers (a pink plate and a teal plate) with mix-blend-mode: multiply, each plate offset by a small registration error (1–3px, different per spread) and textured with an SVG turbulence noise mask so ink coverage is grainy and uneven; large flats use halftone dot or line screens (SVG patterns) at different angles for each ink; line work is pushed through a displacement filter so it wobbles like a drawn line. The signature moment: registration drifts with the pointer: moving the mouse (or dragging/tilting on touch, or scrolling) slides the pink plate against the teal plate by a few pixels across the whole page, with a springy settle, so overprints open and close and the viewer feels the two plates; a small "registration" crosshair mark on a paper tab in the corner (the printer's target) shows the current offset with a numeric x/y readout and can be dragged (or nudged with arrow keys) to misregister on purpose by up to 12px; double-click (or Enter) snaps everything, including each spread's own error, back into perfect register until the pointer moves away again.

Typography: zine-like and confident: huge condensed sans headlines (Impact/"Arial Narrow" stack) in pink overprinted with teal keylines; the cover title is set as SVG text stretched to the full width of the spread, with teal line and dot screens clipped inside the letters; body in a typewriter face (Courier/"American Typewriter"); hand-drawn SVG arrows, underlines, asterisks and marginal notes; page numbers in scribbled circles; crooked paste-up blocks rotated 1–2° with torn tape; crop marks, a colour bar and a plate slug on every spread.

Content: a vertical sequence of 6 "spreads" each sized like a folded A4 page with a visible centre fold and two staples drawn at the spine (on phones the pages stack and the fold turns horizontal): 1) Cover: giant "SPORE PRINT" with a big overprinted fly-agaric-like cap illustration crossing the fold, "issue 3 · the wet month · free or trade", a contents list, "No.3" and a starburst "free or trade" sticker. 2) "How to take a spore print": four steps with drawings: cut the stem, cap gills-down on paper, cover with a glass, wait overnight; with an interactive: press the cap (seen from above on a sheet of paper), a moon crosses for the night, the cap lifts aside and a spore print slowly blooms where it sat as radial lines of dots in teal (animated, each time a different pattern: different gill count, density lobes and draught smear); press again for a fresh sheet. 3) "Five you will meet": profile cards of five mushrooms described by general appearance only (a brown bolete-type with a spongy underside, a shaggy white cap that melts into ink, a bracket shelf on birch, a tiny orange cup on moss, a ring of pale caps on a lawn), with friendly drawings and field notes in the writer's voice; no edibility advice except the firm repeated house rule: "we don't eat anything from this zine. this is a zine about looking." 4) A centrefold poster: a procedurally drawn forest-floor cross-section showing rain, trunks, small mushrooms, a pair of boots, roots, and mycelium threads linking tree roots, in overprinted line work, with the line "the forest is mostly underneath" and pasted labels. 5) Letters (three, with replies) and a hand-drawn weather calendar for the wet month: 31 squares with drawn weather, a pink cap on days something was found, a diary line for each day, and totals computed from the calendar. 6) Back: colophon ("printed in two colours on a machine named Gerald; 200 copies; stapled by hand"), a copy number, a "pass it on" rubber stamp that can be pressed to leave further faint impressions, a "this copy has passed through" list, and the press mark.

Motion: spreads arrive with a slight paper slap (rotate from 3° to resting angle with a fast overshooting ease-out), not fades; mushrooms nod on hover or tap; mycelium lines grow by stroke-dashoffset when the centrefold enters view. Reduced motion: plates fixed at a tasteful static misregistration (the mark can still be dragged), no slap, no nodding, no growth animation, the spore print appears at once. Voice: warm, damp, funny, first person plural.

DESCRIPTION
A six-spread stapled zine laid out on a cutting mat, printed in exactly two inks. Everything on the page, from the full-width cover title to the smallest weather icon, exists twice: once on a fluorescent pink plate and once on a teal plate, multiplied together over flecked recycled paper so that overlaps turn a deep violet nobody paid for. The plates never quite agree. As the viewer moves, scrolls or tilts, the pink plate slides a few pixels against the teal one with a soft spring, keylines drift off their fills, halftone screens beat against each other, and a printer's registration target in the corner reports the error and can be dragged to make it much worse or double-clicked to make it, briefly, perfect. Inside that process sits a warm, funny little publication by two damp people and a cat: instructions for taking a spore print (with a cap you can lift to watch one land), five mushrooms described like neighbours, a centrefold of roots and mycelium growing under the fold, letters, a month of rain, and a stamp telling you to pass it on.

VISUAL TECHNIQUES
- Two stacked SVG plates per illustration (pink and teal) composited with mix-blend-mode: multiply over paper, so overprint produces the third colour
- Global registration offset driven by CSS custom properties, added to a different base error on each spread, with spring-damped motion
- Ink grain: tiling SVG feTurbulence tiles (fine speckle multiplied by coarse mottling) used as CSS mask images, different for each ink
- Recycled paper: thresholded turbulence flecks and stretched-noise fibres as tiled backgrounds
- Halftone dot screens and line screens as SVG patterns at different angles per ink (15° and 75° dots, crossed line screens)
- Hand-drawn wobble from an feDisplacementMap filter applied identically to both plates
- Radial gills drawn with a single dashed, very wide circle stroke squashed into an ellipse
- Cover title as SVG text with textLength fitting, pink flat plus teal keyline with screens clipped to the letterforms
- HTML headlines doubled with pseudo-elements: pink fill on the moving plate, teal text-stroke keyline on the fixed plate
- Canvas spore print: thousands of jittered dots along primary, secondary and tertiary gill rays, revealed from the centre outward
- Procedural centrefold: seeded random-walk roots with tapering widths, mycelium links and wandering forks, grown with stroke-dashoffset; rebuilt in portrait proportions on phones
- Paste-up blocks with torn tape, crop marks, colour bar, drawn staples and fold shading, scribbled page-number rings
- Container-query units so each spread scales like a printed sheet; paper-slap entrance with an overshooting cubic-bezier

INTERACTION MODEL
Moving the pointer anywhere slides the pink plate against the teal plate across the whole zine; scrolling adds a vertical slip that settles, and on touch devices dragging a finger or tilting the device does the same. The registration mark in the bottom corner mirrors the offset, magnified, with an x/y readout; dragging it (or focusing it and using the arrow keys, Shift for bigger steps) pushes the plates deliberately out of register, and a double-click or double-tap (or Enter) snaps the whole page into perfect register until the pointer moves away. Spreads slap down onto the table as they scroll into view, and the centrefold's mycelium grows when it arrives. On the spore print page, pressing the cap runs a short night, lifts the cap aside and lets a new, unique print settle over about seven seconds; pressing the cap again puts it back on a fresh sheet. Mushroom drawings nod on hover, tap or focus. In the weather calendar, hovering, focusing or tapping a day shows that day's diary line and tapping pins it with a pink ring. On the back cover, pressing the "pass it on" stamp thumps it and leaves another faint impression somewhere on the page.
