[dorkbotdc-blabber] Arduino code for LED cube

[R. Mark Adams, Ph.D.]

Cool, Dale- thanks!  I have been working on "3D VU Meter" as well- my 
approach is not nearly as comprehensive as yours- I was attaching 
"chopped" values from the A/D converter to specific frames of animation. 
   I still don't have it working perfectly, but you do get some flicker 
roughly approximating the input music... :-)

As soon as I get access to the machine with the code on it, I will 
upload it to the list.
