Empty field · No myths yet · Your hand
The sky is blank
until you name it.
These stars carry no stories. Drag one to another, close a shape, and give it a name — it is inked into your catalogue and kept here for your return.

The methodEvery star here was placed once, by a single seeded number, and it never moves. That is the whole trick: because the field is deterministic, a line you draw between star 14 and star 92 means the same two stars tomorrow.
So the sky can keep a promise. When you close a figure and name it, only the pairs of stars you joined are written down — a short list of numbers and a word. On your next visit the same seed lays out the same field, the same numbers find the same stars, and your constellation re-inks itself exactly where you left it.
A meridian falls down the centre; hour and degree ticks frame the field in right ascension and declination, the way a real star chart does. The readout under your cursor tells you where in that grid you are pointing — you are not decorating a screen, you are surveying a patch of sky.
Nothing moves on its own. The stars do not twinkle, drift, or pulse. The only thing alive on this page is your hand — the line stretching from your last star, the glow that finds the nearest one, the moment a loop snaps closed and asks for a name.
- The field
- A window four hours of right ascension wide and sixty degrees of declination tall. Roughly a hundred and fifty joinable stars, sifted from a fainter dust of background suns.
- To draw
- Press on a star and drag to another. Release to lay a line. Each new line extends your figure; when a line returns to a star already in it, the loop is closed and named.
- To keep
- Named figures are inked in gold and listed in the catalogue below. They persist until you erase them. Clearing your browser data forgets the sky.
- Ancient habit
- Every culture that looked up drew different animals on the same stars. The stars are a fact; the myth is a choice. Here the choice is entirely yours.
