jumping through hoops

A wonderfully warm winter day. Everything was perfect. Lofty visions of CSS3 animations dazzled my eyes. Nay, what's this? A browser from years ago appears. What's that you say? It doesn't support keyframes? Ghast. Make an animated gif! Oh, wait, we need transparency? Make an animated png!

This is the final outcome (sans history) of half a day spent to ensure experience parity on a super old (Opera 9.8) browser that we absolutely have to support.

It took hours, and it wasn't probably worth it, but I learned so much, and in the end it works pretty well.
