Light panel for pumpkin head R2-D2

First, thanks go out to Michael Baddeley for his great design work on all the droids and especially BB-R2. After printing his pumpkin dome design, I thought it would be a great addition to put some lights behind the eyes, nose and mouth openings....

This is a simple design to mount 5 neopixels in the head, and using a arduino nano, come up with a code modification to the adafruit neopixel Strandtest" example. adding some random generator to vary the lights, it works out good. the files here include the arduino code. use this as is, or add your own little twist.
