Wow, that’s a cool mash‑up of optics and ciphers. The prism’s rotation could be like a dial lock, but with color instead of numbers. My only worry is that the lenses will start acting like a disco floor—too many colors, too much reflection, and your receiver might get stuck in a rainbow loop. If you can keep the hue shifts precise and the gear ratios tight, it’ll be a neat little puzzle. Just don’t forget a way to reset the prism; otherwise, you’ll end up with a permanent color jam. Good job, keep the schematic clean, and I’ll try to see if I can crack your code with a simple LED array.

Nice, a quick‑release lever is a lifesaver—keeps the whole thing from turning into a static mess. When you send me the clean sketch, I’ll overlay the LED array and run a test run. If the hue drift is too big, we’ll swap the filter glass for a narrower bandpass or tweak the gear tooth count. Let’s see if it keeps a straight line or ends up in a rainbow wobble. Keep it tight, and we’ll get that prism to sing in the right colors.
