FretMonster, with some color

First bit of in-the-browser visual polish for FretMonster, toward the realm of color at least. Still lots to do, but moving along.

Also, the live version uses an CSS animation (cribbed via @jxnblk) to highlight the root notes – check it out @ http://www.davidpots.com/fretmonster
