I'm also oldish. But man, I freaking love lights. Of all kinds. I just love making shit out of lights or doing weird things. LEDs and neopixels are amazing. I have permanently installed lights on the house, and entire (small) room in the house dedicated for a honelab with RGB everywhere. It's cool as shit (to me).

But not on my work systems. That would be really annoying. Soft lights and elegant design for me.
