3D may need a new visual vocabulary. Fortunately, this vocabulary is currently being developed.
Coughing up the 3D ticket tax for Avatar means Cameron has made a step in the right direction, but he's just at the lead, not yet at the finish line.
There are already people who can do more with 3D than fancy show effects, but most of them are still doing CGI. For instance, did you see the feathers on the pigeons in "Bolt", or Soren's flight through the forest fire in "Ga'Hoole"?
I love watching this development. I also watched how the South African Soccer WM in 3D mostly failed, and how the "Fantastic Four" Live 3D concert transmission succeeded. I bet MTV has something to say about "Krieger".
I just wish there was more proper CONTENT right now that didn't make me want to pirate it because it's exclusive to some silly hardware.
