Teenage Qix: Lightfish
Actually it's more like 30-something Qix, since the first appearance of this game type was in 1981. Anyway, there's a demo of Lightfish, which is like Qix with Flow's visuals, over on Steam. It throws in some novel gameplay variants, of course, but the heart of it is dividing up the game space to slowly destroy your enemy's territories. It's possibly that this might be worth playing if you need a few moment's distraction from the inexorable horrors of your existence. Or not.
