This sounds like an amazing project and learning opportunity! Reminds me of a halfbaked hardware+software project idea of my own:

- Goal: increase the amount of natural light in my apartment during the day

- Mount a flat mirror on a motorized sun-tracking attachment on south-facing balcony railing

- Set up geometry, software, and motor to rotate the mirror so that it always reflects a beam of sunlight into the apartment, trained on a target area between the wall and ceiling, above eye level of occupants
