A language where a program is a work of art, and every run draws a new edition of it.

An alea program describes a family of artworks. Where you would write a number, you can write a distribution instead: ~between(0.25, 0.4) lets alea decide, once per edition. ~~ decides again at every point of the picture, and choose picks between whole structures.

Then you say what to make of it. The same work can render an image, a looping video, a sound, a sculpture to print in 3D, or a MIDI score that plays in your DAW. Works can use other works as parts, take a photo or a sound as input, and read from a pipe.

It is written for artists first: no setup to try it, plain words for its functions, and error messages that say how to fix the problem.

work Moon {
  let moon  = circle(size: ~between(0.25, 0.4))  // alea decides
  let shade = move(moon, x: 0.08)                 // nudged right
  render image(merge(clouds() * 0.25, cut(moon, shade)), palette: "night")
}
