Visual and Two-Dimensional Programming Languages
A survey of languages where position on a plane carries meaning, from Befunge and Fish to Piet and Hexagony, and where the Funge family fits among them.
Esoteric Languages
Visual and 2D Languages
Other languages where layout, color or geometry carries the program.
ASCII Art Programs
When source code doubles as a picture: how shaped programs work, when the shape is decoration or structure, and a small Befunge example you can trace.
Fish and Other Mirror-Based Languages
How Fish (written ><>) steers its pointer with mirrors and arrows, how that compares with Befunge, and what the two approaches mean for reading and writing code.
Piet: Programming With Colors
How Piet programs are images, how blocks of color are traversed, and how the change in hue and lightness between blocks selects each operation.
Programming on a Hexagonal Grid
What changes when code lives on a hexagonal grid instead of a square one: six directions, different turns, odd edge wrapping, and how Hexagony approaches it.
