I built a tool to store text messages and arbitrary files in scrambled Rubik’s Cubes - a simple form of analog steganography.Each 3×3 face encodes up to 4 characters by combining 6 standard cube colors (6×6 = 36 combos).
The key idea: you only need one face, so you can hide messages by casually placing a scrambled cube in the background of a photo or video.For binary data (images, zip files, encrypted blobs), use the scbase36.py script on GitHub — it works like base64, but uses 36 symbols (because 6×6 = 36).Would love feedback or ideas to push it further.
I also made versions for 5×5, 7×7, and 9×9 cubes — storing 12, 24, and 40 characters per face.Try it out:
