Reminds me of japanese anime Dennō Coil, where kids would draw computer programs almost exactly like the author’s on the floor and invoke them as some kind of enchantement. Highly recommend it!
This must be the preferred programming language of the otherworldly main character of Aphyr's "Xing the technical interview" sequence of blog posts [1]. Would definitely deserve its own entry in the series.
This is incredible, what's the license of the work? A derivative of this (using a forth-like with only recursion) would be perfect for the current game project where I'm lacking a visual representation of spells (both written and animated). Mystical provides the missing piece of the puzzle of how users could write their own spells in a structured way within the game and still feel as if it's part of the game world with the same kind of thinking as in regular programming.
I've been working on one of these too! Mine's based on Dusa, a logic lang which has the nice property that the order of instructions don't matter. This gives a lot of options for making really expressive, dense runes but making a program that lays it out automatically has been challenging. It's also nowhere near as readable as Mystical for better or worse.
For game purposes I've been looking up alchemical and mystical symbols, and I've been frustrated that, while there's a lot of references of symbols, alphabets, etc. themselves, there's little or no presentation of a grammar that would direct one in creating larger diagrams that look like this. This is amazing. It's deeply pleasing that code, represented systematically, would be so aesthetically pleasing.
This is neography meets conlang. Love it. I would really love to see a unique programming language that uses a constructed language with a beautiful script. I had the idea of making one but I never got around to it.
Oh wow, I had to try this and as expected it's amazing. Trying to design interesting algorithms that also look good is a lot of fun, and the result is surprisingly readable.
It takes some getting used to symbols that can be confused when upside down such as b or brackets (like the symbols for begin/end)
Like others I am curious about doing it for a lisp or Forth
I call upon thе blood-moon goddess, for I have but one request. I've laid the altar, charged the crystals, the circle, I have blessed. PLEASE boot this time.
Theologically speaking, there is an important distinction between magic, or sorcery, and mysticism. Sorcery is an attempt to twist or subvert the divine while mysticism is an attempt to uncover it.
For example, Hildegard von Bingen is a mystic while Heinrich Faust would be considered a sorcerer. The distinction is important as mysticism is considered a holy activity while sorcery is considered to be a profound sin.
Meditation and esoteric study would fall under the realm of mysticism, while things like divination or the dishonest manipulation of belief would be considered sorcery.
Very cool - it reminds me of some of the programming-language-like magic systems in Sanderson's books, especially AonDor in Elantris and Lines in The Rithmatist.
This has uses right? A prettier form of QR code? Would be a tad difficult to decode automatically but I definitely like the combination of aesthetics with logic.
PostScript (with its reverse Polish notation) rewires brain on its own (it is top 1 in languages that "made me think different). Adding esoteric visuals is a nice touch.

Also, Babbage with literal gears. Look up for electromechanical computation.

And this idea can probably be applied for any Lisp-like, any stack based language or array language.
With the right structured editor, it could be used for legitimate programming, it might even be more compact and readable at a glance than some code.
