I really dig the cool things being done online these days, but it's really bringing me back to "Site works best in IE4.0" or "Please download Netscape to see this page!". I wish I didn't need 3 browsers to view the Internet anymore.
Lots of these new technologies are still in the tech demo phase, exploring the possibilities. Many of these demos, including this one, serve no practical purpose beyond saying "Hey, check out this cool new feature". When these technologies are actually used in applications, they will be used as progressive enhancements: if your browser supports them, you'll see some neat visual flair; if not, the app will still work and you'll never know you are missing something.
It sort of works for me. Grey spaces where map tiles haven't loaded though, and I'm not sure why. Also you can't move around etc., so there isn't much to look at.
The CSS transforms are hardware accelerated by Chrome, but I can imagine this animation is still a bit too much for an EeePC GPU. Maybe with a static map it runs more smoothly, since GMaps is also a bit heavy. However, running smoothly was not the intention of this experiment ;)
