Fibonacci256 Expanding is a beautiful 166mm circular disc with 256 RGB LEDs surface mounted in a Fibonacci layout.

Three different sizes of LEDs are used: 2mm, 3.5mm and 5mm. The LEDs start out small and close together in the center and gradually get larger and further apart. This gives an illusion of expansion, especially with the right animation.

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. Fibonacci256 Expanding 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.
