Not so much now, but I was majorly fascinated with lights. In fact, there's a funny story that strongly drives the point home. When I was little, my family took me to this community (or maybe college) theater play for children. It had characters from famous fairytales interacting together. It was supposed to a parody; for instance, the Big Bad Wolf came to the Snow White cave, and she told him he had the wrong house, and he'd threaten to blow it down anyway. In between those skits, the characters would dance onstage, sometimes all facing the audience, sometimes in deliberately mismatched partners (Little Red Riding Hood with Puss in Boots, for instance), to fast music and flashing colorful lights. The dance scenes between character skits were meant to function as a theatrical equivalent of song choruses.
Those lights mesmerized me! I ended up missing much of the play, because I was so focused on the moving, flashing lights. I stared at the projectors with a transfixed look in my eyes. As a result, I ended up missing most of the music and the skits in the play, let alone the ironic humor behind the mismatches in partnered dancing characters. My family even had to keep slapping me on the shoulder to bring me back to reality.
My fascination with lights today is limited to preferences for certain spectrums. For example, I can't stand the bluish, hospital-like glow of LED's of any kind, and strongly prefer the warmth of incandescent light bulbs (inside) or sodium vapor lamps (outside).
