LOOM Studio

a tiny language for woven cloth

New here? LOOM describes woven cloth. Warp threads run up and down; weft is thrown across them.
  1. 1Set up the loom: size, warp colours, and the shaft each thread hangs from.
  2. 2Pick row by row: each pick lifts some shafts. Lifted threads show their colour; the rest hide under the weft.
  3. 3Watch it in the Loom tab, step through the code, or open a Gallery piece.
