The wind in the trees, how?

I am preparing to build a number of trees and would like to make them as 'lively' as the ones that I see every where in SL. Many of the species are common to California but I would like to expand this to more varieties.

I am an experienced scripter and 3D artist out in the RL but brand spanking new to the methods in SL.

I have dug through the editor dialog thinking to find a clue but no luck.

Can someone point me to how I can help green up the SL?

Trees are special "linden objects" and the renderer treats them different from any user created object.

I suggest you play with the 1.9.1 preview as I think it impossible to do without "flexiprims" (particularly as the best treemakers in game haven't made anything close in the last three years).

I was afraid that might be the answer, Introvert. What I know of 1.9.1, it might be a possible coarse of action.

Is the the botanical rhyme yours? I like it.
