/*
This demo is best viewed using the FastLED compiler.
 
Windows/MacOS binaries: https://github.com/FastLED/FastLED/releases
 
Python
 
Install: pip install fastled
Run: fastled <this sketch directory>
This will compile and preview the sketch in the browser, and enable
all the UI elements you see below.
 
 
 
OVERVIEW:
This is the famouse Animartrix demo by Stefan Petrick. The effects are generated
using polor polar coordinates. The effects are very complex and powerful.
