As I was looking at [this answer](http://stackoverflow.com/questions/16132190/after-login-user-is-not-redirected-to-the-specific-page-in-php/16132230#16132230) on SO mobile site on my iPhone, an animated profile picture caught my attention.

[Animated gifs are not allowed on profile pictures](https://meta.stackexchange.com/questions/164023/animated-gif-profile-pic-on-stackoverflow-doesnt-animate/164025#164025), but this one managed to show up on the mobile site.
