I am very surprised by finding what PhotoShop latest version can do. The most interesting feature was "Content-awareness".
You can see the overview video here:
A shorter version is here:
I have seen the same functionality from SIGGRAPH papers in 2007, 2008 and 2009, but I haven't seen a practical software to do them. Now Photoshop integrated it and ready to use.
Beside content-awareness feature, 3D features are also impressive.
