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: - https://cube.xtn.sh (3×3 – 4 chars) - https://cube.xtn.sh/5x5 (12 chars) - https://cube.xtn.sh/7x7 (24 chars) - https://cube.xtn.sh/9x9 (40 chars)
