Building a 3 x 3 x3 LED Cube controlled by an Arduino?

I built a 3x3x3 LED cube and tested it. Since I'm new to electronics and micro programmable processors I'm having a difficult time connecting the cube to the Arduino and haven't had much luck getting information fundamental enough for me to grasp. I've tried a few ways and as you would expect, trashed a few LEDs to say the least. Since the digital pins output 5 volts I can't figure out how to connect the  9 anodes and the common cathode per level.  Can anyone help?

I'm having troube forming the 3x3x3 Cube. If anybody knows of any good pictures/tutorials on it, a link would be appriciated. did NOT help with forming the cube one bit.
I had the same problem as you.... I was confused on how to connect each layer together. I fixed this by soldering a 1 inch piece of copper wire to the anodes (the longer one)that runs up beside the led. That way I could connect the layer ontop of that to the wire and not have to run down past the led. Does this make sense?
