A rather good animated GIF of a busy section of tube line (5.8MB) that I
saw illustrating an article about commuting:

Interesting variation in the results from different browsers. Internet
Explorer (IE9) runs through the animation in 5 seconds. Chrome does it
in about 1½ seconds. Firefox won't show it at all; it gives a code 403
error (access denied). Are GIF animations supposed to run at a
particular speed, or does each browser make its own decision?
