Reader Rob H. pointed out this nice little mid-Sunday diversion: Dino Run. After you get the hang of it you realize nothing in the environment will kill you, just slow you down on your panicked quest to outrun extinction. But most importantly, it's a flash game with multiplayer across three servers, although I waited forever for a game to start up.
Still, to the designers, hat-tip for rendering it like an old 4-bit PC game. I dunno, the tone just seems to deserve that kind of treatment. And also note how your dino farts after you chow down on less fortunate sauropods. Hat-tip for that, too.
