Hexagony

Hexagony was created by me, Martin Büttner, in September 2015.

As far as I know it is the first two-dimensional programming language which operates on a hexagonal grid (instead of the usual rectangular grid). To make matters worse, opposite edges of wrap around, making the topology of the source code a weird twisted torus. To make matters worst the memory model is also a hexagonal grid, where each edge holds an integer value. Considering these things, I think the name (being a portmanteau of "hexagon" and "agony") is completely justified.

I have only written a couple of programs in it so far, but my prime checker contains a fairly detailed explanation of the language's quirks.

• GitHub repository. Includes interpreter (Ruby), language specification, example programs and issue tracker.
• Esolangs page. Largely a copy of the README.md on GitHub.
• Esoteric IDE by Timwi which contains another implementation (C#).
