As a boy in the '70s, I enjoyed both building two of the AMT 1701 kits and playing with them with friends.
I did the same thing. The apartment townhouse where my father and I lived had a two foot wide globe lamp suspended over our dining table and was controlled by a dimmer switch. I'd dial it to a faint glow and "orbit" my assembled Enterprise around it, pretending the lamp was a planet. Turn the lamp brighter and it became a star. Have my buddy Kyle oscillate the dial to make the lamp "pulse" and it became the flagship Fesarius of the First Federation.
Shoot, has it really been 40 years?!
