Couldn't sleep, so I tried to debug what was going on with rendering small graphics. That text is on the graphics layer, and it's done using a single "sprite" type with 128 different frames that cover ASCII plus a range of other useful graphics. Since they don't need to move or behave any particular way they're really more "special effect" than "sprite". But as part of my testing, I needed more than just the holodragons, and these one-eyed things sort of happened. Spooky.
