A Different Kind of Chord Book

I just found something neat. It's a different kind of chord book. It's got a really great concept. It shows you (a) what notes are in a given chord and (b) every place that any of those notes is found, up through the 14th fret. This lets you see all of the different ways that a chord could be played. For instance, the typical A major chord is played 2100 (A,C#,E,A). In this different kind of chord book you can see that 6400 (C#,E,E,A) also works, and yet provides a completely different feel. An example of a song that uses both of these A's is on Uke Hunt.
