  Vorto Light
  A DIY Philips hue.

  Like the Philips Hue, you can connect the VortoLight with IFTTT.
  Let IFTTT (or an other service, or youself) post sertain keywords on twitter.
  Thingspeak (and your sparkcore) scouts for those keywords and acts accordingly.
  
  The VortoLight uses WS2812B leds (also know as Neopixels from Adafruit).
  
  Based on 'MagicWord!'
  https://github.com/MrMdR/MagicWord
  Your sparkcore reads Twitter and execute an if/else statement when a matching word has been found!
  (acctually... ThingSpeak reads twitter and gives your spark core a kick to do something...)
