Escape-time fractals powered by a formula compiler. Graphics are visualized using distance estimation, normalized iteration count, and/or atom-domain colouring. Navigation is enhanced by Newton-Raphson zooming: a single action can bring you to a mini-set or an embedded Julia.
sudo apt-get install \ build-essential \ git \ ghc \ cabal-install \ libmpfr-dev \ libgirepository1.0-dev \ libwebkit2gtk-4.0-dev \ libgtksourceview-3.0-dev
The last 3 packages are for the GTK GUI, the CLI version doesn't need them. The GTK version is incompatible with GHC 8.2 due to a bug in that version (8.0 and 8.4 are both fine).
