* decorating your tree or the trees for different seasons, or different holidays around the year. Would love to see more multicultural design ideas than what I grew up with as a white lower middle class American.
I'm going to try and create designs around the wiccan wheel of the year, myself.

* Training trees into shapes, the science, the art, or both

* Pruning trees to increase harvests

* Guerrilla tree grafting to make trees an urban food source

* Meditation with a tree-friend. Could be magical or magic-free

* Different dryads living in different kinds of trees. What would a gingko dryad look like? As compared to a citrus dryad, or a fig dryad? Would a dryad for a tree that has a treehouse built into it feels any kind of way about the family that built the treehouse?

* Tell me about lumberjacks, and public utility workers who cut down or prune trees for concrete reasons.

*Contrast with the previous, tell me about the activists fighting against over logging and corporate greed.

* Tell me about a firewatch tower volunteer, and them learning about and learning to love the trees they are looking after.
