I bought the kit. if you are going to make a rectangular/square martix kinda proejct, you can't beat it.
i also made my own 72 led Charlieplex network in a linear format. think a string of 72 white LED, individually controllable.
Unable to find any documentation on how to wire up a charlieplex network in a linear format, everyone had diagrams for squares/rectangles, so I had to devise my own diagram. I posted it: http://arduino.cc/forum/index.php/topic,99338.msg744912.html#msg744912
The first 16 LEDs are "stacked" to make the diagram shorter.
ALSO, This doesn;t follow the simpler array pattern (1,2/2,1;1,3/3,1;1,4/4,1etc) This diagram's array would be 1,2/2,3/3,4/4,5/5,6...up to 1/3,2/4,3/5,etc. my bad.
I hope this helps.
