Let's start with the Animated Shorts, shall we?
All but Pixar's "Lifted" is up on around the net for you to see (Lifted will play in front of Ratatouille, out June 29).
Disney's The Little Matchgirl can be viewed here.
Blue Sky's "No Time for Nuts"
The entirety of the winning short, Torrill Kove's "The Danish Poet" used to be on the NFB's website. If you didn't catch it, here's at least a small clip:
The Live-Action Shorts are a little harder to come by.

Here's a clip from it:
Two clips from "The Saviour"
And a clip from "Helmer and Son"
Phew! Long post. Enjoy!
