Cheap character LCD displays are more versatile than we give them credit for. Most of the cheapies have a 5×8 character display, which looks blocky but legible when you have an appropriate font. Where it gets fun is that most of the LCD displays also let you upload custom characters.

It’s tiny, it’s monochrome, and doesn’t play the Troika theme (which may be a good thing), but it’s playable. Check out the video below.
