I wish these 3D animation shorts were a full movie. Called Tiny Worlds, it shows miniature sized characters and machines solving normal sized problems. Cigarette flicked on the ground? A tiny submarine will blast it away. Matches left on the street? A mini semi truck will haul it away. Gum on the sidewalk? Let's call the small bulldozer. It's super cute.
Watch them all below. I think the submarine is my favorite.
