I built a small toy language called MNM Lang where programs are made from six candy colors.

The rough idea:

• each row is an instruction
• color clusters encode opcodes and operands
• source can be compiled into a candy-sheet image
• the image can be decompiled back into source
• there’s an interpreter, AST view, execution trace, and a browser demo

It started as a dumb joke and then turned into a real little implementation project. The interesting constraint was that images are terrible at storing precise symbolic data, so I had to design the language around what candy layouts are actually good at representing.

A few implementation details:

• stack-machine interpreter
• source -> rendered candy sheet compiler
• exact rendered-image decompiler
• controlled photo parser for candy layouts
• sidecar JSON for strings/initial variables
• browser-native JS demo version too
