(all made with roflbot, natch. Ghost Light images capped by me; other pics nabbed from the Tragical History Tour (thanks to supersonica and yuxonomei for help tracking that down), A Brief History of Time Travel, and good ol' Time and Space.)
ETA: I have become slightly paranoid about that image I've left outside the cut breaking some people's flists. Let me know if it's a problem.
