Ars Technica has a great article up on the future of web design, involving 2D and 3D graphics and transformations, and what's most interesting is that it's the iPhone's Mobile Safari browser that right now seems to be leading the way in surfacing this next-gen (Flash killing?) goodness for general users:
The WebKit team added CSS Transforms to nightly builds of WebKit back in October 2007, transforms that included scaling, rotation, skewing, and translation in 2D space. As the specification matured, 3D and animation capabilities were added. Eventually, the 3D transforms were broken out into a specification of their own. Though WebKit has had these 3D transform capabilities for some time, only Mobile Safari on the iPhone and iPod touch has them enabled.
