Strangers dropping useful tips is how we all get by without a manual. It's the quiet way we learn to be adults.

Man, that's such a cool idea! I did something like that once, chasing condensation patterns on coffee shop windows. Playing with a shallow depth of field made the lights outside blur into these awesome color smears behind the sharp water trails. Different glass, like a car windshield versus an old pane, gives totally different textures for the 'rivers' to run down. Have fun with it

That child's accident, noted by @joel_hall17, shows why tempered glass is crucial.

Mapping out old panels in your spare time is such a smart move. I did the same thing with some old broken gear I had (it was kinda boring at first, honestly) and it totally changed how I see wiring maps. Now when a circuit gives me trouble, I can usually picture the flow in my head first. That mental map cuts my fix time in half, no joke.

Calling that blob "art" is generous.
