Loom

Loom is a visual esoteric programming language that operates on a 32×32 memory grid. Inspired by Brainf**k, Loom weaves colorful patterns directly into a screen-grid using a minimal, expressive syntax. Each memory cell stores a value between 0 and 31, corresponding to a 32-color palette.

Unlike traditional esolangs, Loom unifies code, memory, and screen into one fabric, literally. Movement, arithmetic, randomness, and drawing are achieved through compact, symbolic commands that produce intricate visual results.

🧵 Language Features

• 32×32 wraparound grid shared by screen and memory
• Drawing via memory: x draws a pixel at current location using (value % 32) as color
• Fully navigable: use <, >, ^, v for movement
• Supports repeat counts (e.g., >23 = move right 23 steps)
• Built-in support for randomness and loops
• Clean syntax: comments allowed using unquoted text; reserved symbols (>, <, etc.) must be quoted inside comments

✨ Operators

Symbol	Description
>	Move cursor right go back to first cell if screen size exceeded
<	Move cursor left go to the end of the line if less than zero
^	Move cursor up go to the end of the column if less than zero
v	Move cursor down go back to the top if screen size exceeded
+	Increment current cell (wraps at 32)
-	Decrement current cell (wraps at 0)
o	return back to the original cell grid[0, 0]
x	display the content of the current cell to the screen
*	for debugging display usful information for the current cell
?	Set current cell to a random number from 0–32
{} [] ()	Loop: repeat enclosed code block while cell ≠ 0
'...'	Quoted strings — used in comments or to escape special symbols

Repeat counts: Any movement or arithmetic operator can be followed by a number (e.g., +12, >5) for efficiency.

🧪 Example Program

The following program generates a radial rainbow explosion from the center outward using color logic, movement, and nested loops:

+{?x.+31[>?x.<[>+<-]>-]v>+}

Explanation

• +{}: Start the outer loop to draw multiple random lines
• ?x: Set current cell to a random value and display it on the screen x
• +31[...]: Add 31 and begin inner loop for the number of cells at each line
• [>?x.<[>+<-]>-]: Use nested loops to draw random cells for each line
• v>+: Move to the next line start from the beginning
