Peace Hand Sign and Other Hand Gestures?

Hi I was wondering what are some other hand gestures other than the V. (non-offensive hand gestures.) The V sign cannot be trademarked but the Heart Sign has been trade marked, therefore cannot be used in other media without lisensing. What are some other good hand gestures that are free to use?

Thanks
P.S
Good examples are in this picture of Country Joe And The Fish http://upload.wikimedia.org/wikipedia/commons/3/35/Countryjoe.jpg

 

on a sorta related topic, i know that VW camper van drivers, if they pass eachother on the road put up fingers at eachother- the amount of thousans they paid for the van! how fun ? sucks if you paid up to a grand or over ten grand though, but oh well

so if you get a vee dub, you can do that when you see another

 

The touch pad on my laptop supposedly understands "gestures" for scrolling and stuff. There's only one gesture I want to make to my computer, and it doesn't understand that one.
