I finished adding the LEDs to the limbs. I tucked in the negative leads into the brass tubes. Then I trimmed up the "roots" and added resistors and wrapped them around a breadboard. Since I am looking for some PWM on 9 LEDs and I don't have a board that could PWM 9 channels at a time without charlieplexing, and I am too late for the parts bin contest. So I ordered a TLC 57911 from adafruit and I will drive it with a Padi I think I can mount on the post.

Perhaps a little decoration with some PLA? I dunno.
