Slime molds are protists who move along something decaying, like a dead tree, consuming it. When they are ready, they pull their mass into a stalk with a bulb at the top of it and send out spores...baby protists. Make a closeup 3D of a slime mold, munching decaying matter, reorganizing, forming a stalk and spewing out spores.
It could emerge from the sea floor, spewed out by a vent in the sea floor, run into bioluminescent algae and fish; be consumed by a whale and discharged; run into a shark; get tangled in seaweed; be collected into a gathering wave and smashed onto a sandy or rocky shore.
Make a 3D of emotions as you see them: love; joy; loss; fear. Use shapes, colors, iconic images. Move through the emotions in 3D.
Depict a battle scene, especially one that hasn't been done repeatedly. Create a scene of Celtic warriors in their Torcs; Amazonian indian tribes fighting in the jungle or completely invented warriors battling for a reason that comes from your own imagination.
