Yes you can use more leds, but then (in case that you would like to use this setup [one led to one digital pin]) you'll need more digital pins (Arduino MEGA).But you could also buy or rebuild the LOL Shield (Lots of LEDs) for the Arduino Uno (which has 126 leds on just one Arduino).

The World's Smallest 4x4x4 RGB LED Cube
At first I want to say 'Thank you!' for this Instructable, I will build a big panel, which can be mounted on my wall, that visualizes the Music.But I also changed something that I can highly recommend:I wanted to have both audio-channels (left and right) visualized but I also wanted to have the stereo sound on my jukebox so I added a 1N418 diode to one pin of the audiojack and tadaa it works just fine. You can see my version of the sketch in the picture:

EDIT:Somebody else had the same question and you said that you already made a Video how to do it.http://autode.sk/2eNZmBF
I'll print this later.Is there a way to Export it to a STL-File (not only to a programm)?
