Recommend your favourite informative and interesting websites, browser-based games, online videos, free and legal music downloads, tv shows & films (on tonight, obviously), etc etc to the likes of me and other who will inevitably be awake... all... night...

All I can throw up is that The Crazies (George Romero's 1974 proto-Dawn of the Dead) is on Film4 again at 1am! (for fans of low-budget 70s B-movie action, and Romero films in general) I watched it only a month ago though, so... use this thread to recommend things to do online or in front of the tv.
