Migjoke

This mysterious world from 2002, bundled with a .BAT executable but no text file, is a single board that uses a custom font to create an image of someone playing Super Mario Bros. on a tall mirror with two faces smiling at their reflections in the glass. It's likely that "Mig" stands for "Mirror Image Games", a contemporary ZZT company, and that this is a riff on that name. Beyond that, it's anyone's guess as to what this was for... or whether this was intended to be released at all.

(Trivia: the font is clearly an edited copy of MegaZeux's default font, and thus has graphics from that font which are never used.)
