This recent Unicode-proposal about 8-bit character sets is a great initiative, although it only includes platforms that were popular in USA and UK. For now. ;) The uncredited PETSCII Darth Vader is by Ailadi, btw.
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.
