For my animation in Unity I made a character who if you don't look too close could be me, and focused on the idea of this character planting a virtual garden in AR. I got the animations to work (digging and planting seeds, crawling, planting a plant, get up from crouching to a stand, planting at tree, watering the plants) with some assets downloaded from the Unity asset store. The next step would be to develop it as a game/meditation/art piece where you can move the character with key strokes, and possibly time the growing plants or trees to grow after you choose the "plant tree" animation, etc, so it could be a little interactive garden that responds to your actions.
