If you cannot view medium pages, an alternate version of the article is here: http://www.lord-enki.net/medium-backup/2018-04-12_Kaukatcr--an-experiment-in-language-design-for-multi-dimensional-spaces-cc038caafff9.html
It is intended to act as a brief overview of the most interesting aspects of the language – which was never used and only ever existed in prototype form.
In response to some questions, comments, & corrections on mastodon, I have expanded the article. In particular, I added some context for people unfamiliar with Project Xanadu, embedded videos explaining and demonstrating ZigZag, and added footnotes explaining some mechanics and details that aren’t directly relevant to a breezy intro to the language but might be misunderstood by people unfamiliar with ZigZag in general.
