BTW, how are you thinking about anchoring your trees to the playa?
I did half-scale models and came to the conclusion that the playa was tougher than my initial slotted construction had taken into account. I thought of 1x1 bracing along the slot, but ultimately reconfigured so that each tree is a 4x8 cutout anchored to a pair of 2x4 or 2x6 triangular braces. One, possibly two, corners of the brace will be either ziptied (with the UV-resistant ties) or bolted to a studded T fence post.
For lighting, well, I'm going with supersimple. I'm going to anchor a solar box (firmly!) and use solar LED lights, either with a top 1x1 cross brace between two trees or perhaps dangling down inside the triangular tree structure. I see the biggest issue as making the lights hard to walk off with, and non-tempting to try tugging on to take.
What y'all are doing is an order of magnitude more fun and complex! It's hard for introverts like me to form an art collective, tho I hope to gather helpers and co-creators as I get more and more done. I'll be at Maker Faire in San Mateo in May, and hope to grow a merry band of interested artists there (fingers crossed!).
