It demonstrates the 'nature movement' used in "Rallentando, a restoration" project by Out of the Box Productions. You may use any element of it. Note that the leaves and grass move as if in a gentle breeze, the upper right corner clouds evolve, and there are random birds flying through the scene.
It will open with a Display Console Window with this message, simply delete the Display Console Window node after reading.
Note: the 'speed of movement' node is actually stv.MathChangeSpeed node found at the location noted by khenkel below.
