Build a fantastic light-up fuzzy scarf with seven different color modes.  Easily switch between modes with the press of a button.  With a little easy code hacking, you can even create your own color combinations.  

Warning:  Wearing this scarf in public will get you noticed.  Children will follow you around like you're the pied piper.  Adults and paparazzi will chase you down the street in order to get a photo with you.  Minstrels will sing ballads about the glow you left in their hearts long after your batteries die.  

Prepare for the madness of instant glow-fur celebrity.

For this project you will need:
