I've seen so many wonderful LED projects created by so many talented people. I can't believe I'm the first person to put together this low hanging fruit of a pun project.
Thanks to my cousin Ross Mukai for using his Glowforge to print the Zeppelin pieces.

I used the "level shifting chip" configuration with a 1000 microfarad capacitor on the 5v input and a 100 ohm resitor on the digital out from the Raspberry Pi.

Follow the link to the GitHub page, there is a very complete set of installation instructions. The instructions and installer made everything easy for me.

Used as inspiration for the model I finally created.

The model is based on .125" sized plexiglass, but was actually cut on 3mm material (.118")

Problems with this model:
1. Center lights are lame
Original concept called for each cell between the struts to be individually lit. This proved too difficult for my skill and time. A 3d printed insert that uses a series of blades, and was then wrapped in a diffuser could have provided the proper effect, but I did not investigate further.
2. Kind of too pointy
Dimensions of the Zeppelin create a model that is too pointy. A more rounded nose would look nicer.
3. Model difficult to assemble
The tail and nose should be replaced by "caps" that allow the struts to come together equally. Lining up the nose and tail pieces ended up with a mass of glue being used to "cheat".
4. Programming does not use lights effectively
Using the "Scroll_Quad" Visualization creates a decent effect, but ideal system would have each ring reacting individually. Also, center section could be divided to better represent areas between cells.
5. Plexiglass Struts break too easily
The notches for the struts create a severe weak point, and broke many times during assembly. A method to reinforce those areas will make things a lot easier.
6. Clear Gorilla glue works much better than Acrylic Adhesive.
Acrylic adhesive is essentially chemical welding. Clear Gorilla glue is much easier to work with and dries clear.
7. Hot glue is fine for interior ring lights.
Trying to use clear Gorilla glue for the LED lights is not worth the time or mess.
8. Diffusing on the tail fins could be better
I was not sure how to configure the tail fins to properly show the LEDs. As such, they do not show up very well.
