The 1986 retina screen: the WY-700 video card/screen gave the PC a 1280×800 resolution, and a text-mode of 160 columns by 50 lines. It had a built-in 16×16 font (download), and you could even use your own custom fonts. The high-res modes only supported greyscale, but who needs colours anyway?
So this is a joke, of course, but I do love Shark Aquarium. The details are so scant, and the sharks are basically just grey lines, but it still has more of a sense of place than it’s probably meant to.
