Text is written in by hand, ink bleeds into hand-made paper, and deleting a file cuts its name through with a sword. Under the art is a real terminal with tabs, splits, regex find and true colour.

  • Strikes what you deleterm a file and every mention of it on screen is cut through.
  • Every theme, its own wayTsushima, Chalkboard and Logbook each animate in their own style.
