Fibonacci64 is a beautiful 86mm circular disc with 64 WS2812 RGB LEDs surface mounted in a Fibonacci distribution.
I have created several LED art pieces in Fibonacci patterns. They are all very labor intensive to create, and so are fairly expensive and limited in quantity. I wanted to come up with a Fibonacci layout that was at least slightly easier to create, and therefore more affordable.
I have RGB LEDs in just about every form they come: strips, strings, rings, discs, etc. The LEDs on most discs are arranged in very regular rings. Fibonacci64 is different. The LEDs are arranged in a Fibonacci distribution. The makes the layout very organic and seemingly messy. But with the proper animation, spiral patterns emerge with spectacular results.
Two separate three-pin headers are provided. One for 5V, Data In, and GND, and the other for 5V, Data Out, and GND. The Data Out pin can be used to connect more LEDs.

The open case is built with 3mm black LED acrylic diffuser, black nylon M3 standoffs, black metal M3 screws, and acrylic back plate with wall mounting hole. Available as kit or fully-assembled.
