Animating a Space Tree Pro tree

The animation is not the best in the world but it does show how easy it is to animate a tree that was generate with my Space Tree Pro add-on.
The steps that were take were simple:

• Create a lattice object and move/scale it so it enfolds the tree and its leaves
• Add a lattice modifier to the tree: select the tree and then the lattice, type Ctrl-P, choose lattice
• Add a lattice modifier to the leaf emitter: add modifier, select the same lattice object
• Add a shape key to the lattice and let it deform the objects
• Keyframe the shape key on the lattice
• Optionally: keyframe the rotation on the Leaves particle system
