月窓
tsukimado — a small window on tonight's moon
Press the crescent in your toolbar, and tonight's moon
rises in a small indigo window — not a photo,
but drawn on the spot from the moon's actual age.
The moon in this window is drawn at its age right now.
- The moon as it is
- The terminator is computed and drawn fresh each time, so the shape shifts a little every night. A faint earthshine blue lingers on the shadowed side, and stars flicker through drifting haze.
- Traditional phase names
- Thirty names from new moon to old, lit in vertical script — including the waiting lineage of the Stand-and-Wait, Sit-and-Wait and Sleep-and-Wait Moons. In English, each name is a translation that keeps its meaning.
- The moon's sign
- Computed from the moon's ecliptic longitude — "Moon in Scorpio", in a single line. It moves one sign along roughly every two and a half days.
- Next new & full moon
- Dates and times from astronomical calculation (accurate to a minute or two). On the day itself, a quiet sparkle says "Tonight is the full moon." No permissions, no network — everything is computed on your side.
