So rather than studying for the exams I have next week, I decided to mess around with LEDs. I used this code with a diffused RGB LED (put a ping pong ball on top of it for more diffusion and it also looks cooler).

Edit: Found this online today, turns out someone else had the exact same idea of using a ping pong ball as a diffuser! There’s a more detailed write-up, with pretty diagrams and stuff, if anyone is interested in learning more.

I also tried doing this with an RGB LED but it just resulted in possibly seizure-inducing effects. It probably works better with three individual LEDs.

  1. Can you pull off something a bit of a bigger scale other than a ping pong ball?

  2. hmm… How about a colorless yukkuri cutout?
