It's certainly very cool, but is it really that useful? Or I could just be missing the bigger picture. I actually hope that's the case so I can learn something new today. But it just seems to me like making a png/gif image is much easier and more practical. I do love to see technology pushed to its limits though!

I guess one of the cooler applications of this shape making method would be the ability to transform one shape into another very smoothly with a relatively small filesize (as opposed to an animated gif).
