Varigen is an esolang by User:PythonshellDebugwindow. It is an uncomputable output-only high-level object-oriented string-rewriting non-textual pseudonatural self-modifying programming language with graphical output that uses concurrent programming, a deque, a tape, and a stack.
Programs in Varigen take the form of images containing code written in ASCII using the Comic Sans font. In this article, the instructions are displayed in text in a monospaced font for ease of writing.
All these instructions should be self-explanatory, being in a natural language.
[X|Y] means match X or Y,
[X|Y|Z] means match X, Y, or Z, and so on.
[X]? means match X or nothing.
[X]* means match X zero or more times.
<string> means match a string (delimited by "" double quotes),
<integer> means match n integer (matching
<var> means match a variable,
<value> means match a string/integer/var, etc. Types are Qubit, String, and Bit, Fixed Point at N (N=0 for integer).
nil acts as a "black hole" variable, in that writing to it does nothing and reading from it returns a special value (

Interpreters can optionally implement STDIN as a (non-standard) file, such as
.stdin, that when read from (either a line, a character, or the entire file) returns user input (reading a character returns a live character input) and when written to does nothing.
These examples use the proper Comic Sans image format.
