Back around 1980 or so I got an Empire Strikes Back paint by number kit. The most exciting part was that it came with glow in the dark paint for the lightsaber and some other details. When I was done I still had some glow paint left over. I decided to put little marks all over my room to help find my way around in the dark. Door knobs, light switch, edges of furniture. My parents never hung around in my room right after the lights were turned off so I don’t think they ever knew.
