TITLE: ICHIGO ICHIE — a zen clock on washi paper
PROMPT: Create 'ICHIGO ICHIE' (one time, one meeting), a zen clock on washi paper: huge thin hours and minutes fading in with a breath cycle, a slow enso circle drawn and dissolved every minute, seasonal kanji watermark, and a poetic line that changes with the hour. Palette: washi warm white, sumi ink, one hanko seal-red accent. Interactions: hover reveals a minimal control ring (enso style, sound, grid view); a breath-guide mode pulses a soft circle at breathing rhythm with optional gentle chime on the hour (WebAudio, gesture-gated); clicking the seal flips to a day-grid view showing the week as quiet ink squares. Time as ceremony.
DESCRIPTION: A single centered circle of time on warm washi: huge hairline hours and smaller minutes in Mincho serif, a vermilion seconds mark, and a weekday line beneath. Every minute, an enso — the Zen circle, open by design — is drawn stroke by stroke around the clock over 58 seconds, then dissolves as the next minute begins; the ink never quite closes, echoing ichi-go ichi-e. Behind everything, a giant seasonal kanji watermark (夢/朝/風/月 by time of day) breathes at 5% opacity, and a poetic line in Japanese and English rotates every minute, cross-fading like ink drying. The whole clock pulses subtly with a slow breath cycle. Hovering the circle reveals a minimal enso-style control ring — ENSO (ceremonial redraw with chime), SOUND (gesture-gated hourly bell), BREATH (a soft red circle expands and contracts at ~4.5s per cycle), and WEEK. The hanko seal in the corner, printed in seal-red with 一期一会 vertical, flips the page to a seven-day grid where each day is a quiet ink square that fills as the week unfolds — today in seal-red. Paper grain from layered repeating gradients keeps the surface tactile without a single image.
TECHNIQUES: SVG clock face with a dynamically generated arc path (M/A commands recomputed each frame from Date.now); enso stroke drawn over 58s with a deliberate gap and opacity dissolve in the final 7%; breath-cycle opacity pulse on digits; time-of-day kanji watermark with slow cross-fade; hourly chime and minute-bell via WebAudio sine oscillators with 3.2s exponential decay, AudioContext created only inside click handlers (try/catch-guarded, off by default); hover-revealed control ring in pure CSS; week grid computed from real calendar dates with ink-fill height mapped to elapsed fraction of day; prefers-reduced-motion freezes animation loops to static states; system serif stack (Hiragino Mincho / Yu Mincho / Georgia); responsive 360px→4K with clamp() and vh-based type.
INTERACTION: Watch — the clock keeps real time, the enso draws itself each minute, the poem changes each minute, the kanji changes with the time of day. Hover the circle to reveal the control ring: ENSO redraws the circle ceremonially with a chime; SOUND toggles the gesture-gated hourly bell (rings once on enable); BREATH starts a pulsing guide circle at breathing rhythm; WEEK opens the day grid. Click the red hanko seal (or WEEK) to flip to the seven-day ink-square view; CLOSE returns. Keyboard: the seal is focusable and activates with Enter/Space.
