Obscura

August 20, 2017

Obscura made an appearance on Joy of Computing on January 18, 2020, and then got a retweet by the creator of Elm, Evan Czaplicki 👻! To me, this says a lot about the playfulness of the Elm community.

A game I wrote in Elm to learn a little more about the spooky side of functional programming.

You are a ghost in a dark universe governed by math and peopled by dullards.

Guiding principles

The position of the dullards is determined by simple mathematical formulas. For instance dullards might appear arranged in a semi-circle, a spiral, or a sinusoidal curve, but never in an ad-hoc senseless formation.

Nothing is random. The position and behavior of dullards is defined by pure functions. The only variable is user input.
