CSS3 offers some serious opportunities for mis-use with the transform and transition properties. Likewise, there are serious opportunities for really visually cool renderings.
As far as I can tell, only Firefox3.1+ (v3.5b) (Gecko 1.9.1b4) and Safari4b support the transforms, and only Safari4b supports transitions. Both browsers use proprietary prefixes for the draft properties; -moz- and -webkit-.
