Yea, I've found when one posts a picture that Pinsiders can find the craziest of details. It's not a problem; rather a demonstration of the diversity of thinking we each bring to the community - so really it's kinda cool.
Second picture in post #75 helps exemplify a thought I omitted from the previous post because I couldn't easily describe. Looking at your fortress walls downstairs I noticed they won't be floor-to-ceiling and wondered if that space could be usable ... something like that display shelf behind the machines in the picture. Maybe lighting the room by fixtures in that space so you don't have the overhead light can problem that so many of us face in our basements.
Your timeline-based theme sounds neat. Also interesting is how the tastes of game themes has changed - your pics include hockey, basketball, baseball, and bowling. Nowadays the themes primarily seem to be bands and movies/TV. Interesting to try to interpret for a larger societal understanding...
Pinside use tip: when I post pictures I try to add text to the 'caption=' tag so people can more meaningfully reference the picture. If you type nothing hovering over the picture just gives the server's filename; with a caption hovering gives the text you type.
