Swing with tree and pose - scripted

The swing comes in 2 parts (the swing and the tree) 4 + 6 prim. You can use the swing by itself attached to another tree or a porch, or use the tree to place it wherever you want.
The movement starts when someone takes a sit. If you want to stop it have to touch the swing. Touch again to start. With nobody on the swing the movement will stop automatically. All prims are modifiable.
