Ruled Notebook 3
The self-lengthening ruled sheet, now with a full set of controls: faces, rule patterns, paper, margins, alignment, line numbers, binding holes and PNG export.
Starlight Relay — Ending
An 82-second anime ending for the same show that doesn't exist: the runner from the opening and her relay team-mate walk home along a river at blue hour, watch a train cross the bridge and share a pair of headphones under the stars — a 3D rig drawn at human proportions, a ray-traced GLSL background and a sampled-piano ballad.
Starlight Relay — Opening
A 66-second anime-style opening for a show that doesn't exist: a flat, hoodie-wearing heroine dances while her pastel city boots up into a neon cyberpunk night and melts into a city-pop dusk — drawn live in Canvas 2D, scored with Tone.js, finished with a WebGL shader.
Ruled Notebook 2
A ruled sheet that is as long as the writing on it: set the face, the size and the rules, and the page finds its own length so nothing ever runs off the bottom.
The Sunbeam Tour
A fictional setlist archive kept from the cat's side of the house — seven booked dates, six venues, one cancelled show, each night logged track by track and printed as its own gig poster, billed by length so the longest track of the evening headlines it.
Ruled Notebook
A plain lined notebook page — what you type in the box appears on the ruled paper, with the font, size and line spacing all adjustable.
Nakigoto Radio
A late-night talk programme that exists only on tape — three two-minute episodes, spoken in Japanese, each one complaint about how the world is arranged now, followed by the one thought the host has managed to have about it; on the third night a second host arrives to cheer things up and fails. A synthesised voice slowed on a tape deck, a four-chord bed that never resolves, and a J-card with the transcript printed on it.
Point and Say
A pocket phrasebook for absolute beginners in Hindi — fifty everyday and travel sentences, each carried by Devanagari, a katakana reading pitched at how the words are actually said, an English gloss, a word-by-word breakdown and a note in Japanese on why the sentence takes the shape it does, with the grammar it uses threaded through all fifty and twenty-two questions to answer one at a time.
Swash Zone
Eight wave trains summed over a sloping bed: each one shoals as the bottom rises, steepens past the depth that can carry it, breaks, and runs out as a sheet across the sand.
Perfecting
To perfect a sheet is to turn it over and print the reverse. This one turns the Earth: nineteen stations set beside their antipodes as a two-plate register, with the section through the centre drawn between them, and every plate pulled from the public map embed — no key, no API.
Sight-Size
A still life is arranged on a cloth, lit, and drawn the way an atelier teaches it — block-in, contour, shadow shape, then modelling with strokes that run round the form. When the sheet is finished the group is struck, a new one is set up, and it starts again.
Loop Engineering for Claude Code
A link-verified digest of Claude Code loop-engineering practice for team development — the agentic loop, verification gates, CLAUDE.md/hooks/permissions, and the eval harness that keeps them honest, with all 50 sources checked.
Cross Reference
One month of the links page read straight through and set out as a monthly bulletin — thirty-two sources sorted into seven departments, each under its own title and annotated in Japanese prose written for this page rather than quoted from the source, and indexed by the six arguments that kept recurring and the departments they run through.
Box Score
The same run of machine-written stories as the Morning Edition sheet, taken as figures instead of prose — every score distributed, averaged and ranked on one statistical page, where choosing a measure redraws the field and choosing a story follows it through every plate.
Morning Edition
The recent run of a machine that writes one short story every morning — each set beside the three Aozora Bunko texts it was made from, the notes on what it took from them, its critique and its scores, in a three-column sheet that never grows longer than the screen however many mornings it holds.
After Hours
A fictional 1997 corporate website — a company that manufactures the sound of shopping malls — and six operators that push it through the transformations vaporwave is actually made of. At zero it is a sober Japanese business homepage. Every pink pixel that appears after that is the output of a process you can name: dye densities decaying, chroma bandwidth collapsing, halfwidth Latin falling into ideographic width, tape slowing, a room getting larger, a loop cut before its cadence.
Running Hand
A second handwriting generator, built the other way round: nothing is warped or thresholded. Every character is a path a pen takes, and the ink is whatever a nib leaves while travelling it — slowing into curves, drifting off the line, keeping its gaps unevenly, joining one roman letter to the next, and finishing every Japanese stroke with the 止め, 払い or 跳ね that belongs to it.
Fair Copy
A copybook that writes out whatever you type: every character starts as a printed Mincho form, then gets a slant, a size, a baseline error and a wandering outline of its own — fifteen sliders for the unsteadiness of a hand, and not one line of font.
Rosette
A press proof that never dries: a folded sheet turns in the light, and every frame is separated into ink plates, screened at its own angle and printed back onto paper — set the screen angle a few degrees off and the whole sheet breaks into moiré.
Polygon Recon
A single frame from a film that does not exist — a flat-shaded polygon city shot on a virtual camera, printed with haze, halation and grain.
Tide Garden
A naturalist's plate that paints itself: seaweed, fans and anemones grow across the sheet in watercolour and ink, the tide washes over, and a new garden starts — endlessly, without being asked.
Watching Brief
A rescue excavation played as a deduction game. Buried features lie in straight runs that never touch, the figures you dig up tell you where, and a contractor's machine strips one row of the site every few days — whatever you have not excavated or correctly marked by then is gone from the record.
A Hundred Sittings
One sitter, engraved once for every year from birth to a hundred. No photograph exists of them and none was used: each of the 101 plates is cut on the spot from a mathematical model of a face, and the scale under the print is a century long.
Kalvard Weather Bulletin
The weather page of a region that is not there. One atmospheric model runs the clock forward and every panel reads off it — the synoptic chart, both satellite channels, the radar, the hourly meteogram, the warnings and the seven-day outlook.
Marble Image Generator 3
A quarry sample press that keeps cutting new stone on its own — hold it when you like a slab, then save it as a print-resolution PNG.
Lumen Drift IV
The fourth journey of the little light — wear one of three hues, walk on the glass that answers your colour and straight through the glass that does not, refract yourself off prisms, and take the Kaleidoscope apart.
Chart Datum
Survey an uncharted strait from a small launch: the seabed is invisible until you sound it, the falling tide redraws the coastline under you, and the sheet you produce is the score.
Galley Proof
Paste any text and it comes back as a printer's galley — every invisible, counterfeit or accidental character struck in red pencil, the correction written out in the margin. Set each mark or let it stand, then copy the clean revise.
Reading Log Timeline
A vertical timeline of books read, month by month. Cards float freely beside a yyyymm axis; tap one to unfold the reading memo.
Eight-a-Side Soccer
A full top-down 8v8 soccer match — dribble, thread through balls, and steer your shots past diving keepers, with corners, throw-ins and a CPU team to beat.
