The application in the first link is a live controller of the lights in my house. Live as in anything you do in it changes the lighting in my house right now. Any changes you make I can see here. The web application, served by my pi, also returns the neopixels live data being processed so you can see the effects on your end.
I will be posting a guide plus all the source code soon. I need time to put it together. Also, I might hook up a web can so you guys can also see the real life lights change in my house as you edit or alter settings.
