This webpage is devoted to an artwork inspired by the Babylonian creation myth: The Enûma Eliš. Essentially it's a gallery that uses some Elm code to display and describe aspects of each of the panels on seven separate clay tablets that make up the piece.

If these details haven't convinced you to enable local script sources, then I bid you farewell, and safe travels. Remain vigilant!
