Too bad the icons aren't animated (at least I don't think they can be) because then we could have the Amiga 2.x kickstart animation be the icon.

It's just like that, but the floppy disk moves up into the floppy drive.

Anyhow, I think the big colored Check mark would be perfect, or the Amiga boing ball. The UAE4ALL one looks a little overly busy to me.
