I wanted the camera to follow the action in this animation (similar to how the camera follows the Kite in Dan's Kite 2D animation). The animation begins with a raindrop falling onto a leaf. The pressure from the raindrop causes the leaf to move downwards. The raindrop falls to the ground. The camera follows the spores as they disperse from the underside of the fern, and fall to the ground. The spore grows into a gametophyte. Another raindrop falls and hits the gametophyte this time carrying sperm with it. It then falls to the ground and fertilises an archegonia.
