I love hands...
I think the human hand is one of the most expressionist and aesthetic part in the human body. They can "say" so much in pantomime, are very interesting to look at and you can tell a lot about a person just by looking at his hands (and don't forget there is an entire language based upon the hands alone! - the sign language).
At AnimationMentor we've learned about making intersting and non-cliche poses (among many other things) which I totally agree - it's so important to think while blocking you characters poses.
I've found information about hands in several blogs during the last few weeks, and I wanted to share it with the rest of you.
Here are several samples I've found, I even try and eye-copied the poses I found to be the most interesting in my opinion.
