at some point in the mid 1980s there was a computer store in the strip mall by the movie theater where I worked as a teenager, with (what I believe was) an Apple II and monitor set up in the window, showing images all night; pie charts, digitized photos, the usual 1980s home computer imagery, and a piece of Space Battleship Yamato fan art. Seeing that image out of the corner of my eye coming from a darkened storefront sometime in the 1980s was unexpected, to say the least.
