This is not entirely true. The minimum specifiable delay for a frame in an animated gif (other than 0, which just means "as fast as possible") is 0.01 second, which is the setting in the gif linked above. However, most browsers that encounter this will automatically increase the delay to 0.1 second. This is done for compatibility with old versions of Netscape. According to [1], Firefox, Opera and Chrome will accurately display delays as small as 0.02 seconds. Safari and IE will accurately display delays as small as 0.06 seconds. Here is an alternate version of the above gif that displays the animation at 50 fps in the first three browsers listed above: http://i216.photobucket.com/albums/cc41/Peristarkawan/j29-2.gif And here it is at 17 fps with 2/3 of the frames removed, for the benefit of IE and Safari: http://i216.photobucket.com/albums/cc41/Peristarkawan/j29-6.gif [1] http://nullsleep.tumblr.com/post/16524517190/animated-gif-minimum-frame-delay-browser-compatibility -- https://mail.python.org/mailman/listinfo/python-list
