:/ Mmm...Sorry, but I don't really see the practical use of an item that requires an extension to work and even then isn't available to many browsers...It's a neat trick though.
Ahh, the advances of technology we have made over the last few decades. Soon, the age of limited-color GIF animations will be at its end, and its replacement will be this wonderful format of animated image file - the animated PNG!
...At least, when all browsers support it. ¦D
