Arduino Neopixel 7 Segment Display

I want a BIG display, and thought the standard 7 Segment display with boring low color count would be too tame, so have gone for using Neopixels (WS2812B) to create a suitable display that will scale in size..

This is the prototype, I do need to make some changes..
