Animated Shortcut Icons

Question

I was just creating an shortcut icon (the icon displayed in the head part of a page before the page title) (EDIT: I mean favicon...) for a webside, when I was thinking about animated shortcut icons (acually I don't know if they are called like that...).

Even though my intuition told me that this is probably impossible, since I haven't seen it being done on any web pages so far, I wanna be sure :^)

I have actually thought about a things that might in theory help to find out if, or how it's possible:

Using a gif file

There might be a way to make it work using a gif, but probably not. That's too easy. It would be widely-used...

Changing the icon tag using js for every frame of the icon animation

This would actually be my best guess, but I can't get it to work...

Changing the icon image on the server 10 times per second

Forget about this one.

Find out how the loding icon animation is done

Well, it's probably browser side and hasn't todo anything with html/js, but who knows?!

So, that's everything I could think of concerning shortcut icon animations, hopefully you can make sense of it :)

This icon is actually called [`favicon`](https://en.wikipedia.org/wiki/Favicon). :-) — Ruslan Stelmachenko, Jan 02 '17 at 20:50

Found this question here: http://stackoverflow.com/questions/1837261/how-to-animate-a-favicon 2009, says firefox only. Within that, this answer has a JS version and is from 2016. http://stackoverflow.com/a/36489898/3136874 — Sterner, Jan 02 '17 at 20:56
