Arduino 7219 Led Drivers For Mac
MAX7219/MAX7221 are compact, serial input/output common-cathode display drivers that interface microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs.
If you're building an LED cube you're probably going to be using a decent amount of current, so I'd look at LED drivers instead. They're like shift registers but designed specifically for driving LEDs. My favourites, although they can be more expensive, are the MAX7219 and 7221 (7221 can provide more current than the 7219).

Each one supports up to 64 LEDs, you only need one current-limiting resistor for all 64 LEDs, there's digital brightness control, and they're daisy-chainable so you'd only be using 3 pins from your Arduino.
There are also libraries available for Arduino and they're pretty easy to use. Actually I think you misunderstood. The max drivers are common cathode so you're only hooking one end of your LED into it - the anode. The cathodes of your LEDs are all tied together to ground.
The drivers have 8 'Digit' pins (dig0 - dig7) and each one of those has corresponding 8 'segment' pins (segA,B,C,D,E,F,G, and DP). It cycles through the 'digits'. When it's cycling through a digit, it will light up its corresponding segment pins. Edit: misspoke, the digit pins are connected to the LED cathodes, the segment pins are connected to the LED anodes. No way the cathodes are all tied together to ground. How could you control 64 LEDs through just the 8 segment pins?
What you must have meaned is the cathodes connect to the digit pins in bunches of 8, and those pins provide ground one at a time, and then during that time provide high on the appropriate segment pins. But what I don't understand how this can be used to control a 8x8x8 cube, which is essentially a 8 cathode x 64 anode array.
Led Drivers For Lighting
Your first instinct is to hook up the digit pins to the 8 layers of the cube, and then divide the 64 leds of each layer to the segment pins of 8 max controllers. This seems like it should work, but soon you realize there is no quarantee that the controller chips are in sync. Each has its own timer so they will be activating different layers at the same time, interfering with each other.

How to Control a 4-digit 7-segment LED Display with a Max7219 Chip In this circuit, we will show how to display numerals on a 4-digit 7-segment display using a Max7219 chip. The Max7219 is an 8-digit LED display driver, meaning it can connect to and control as many as 8 digits. In this circuit, we're simply going to control a 4-digit 7-segment display, however. Components • Max7219 Chip • 4-digit 7-segment LED display • 40KΩ resistor • 10μF capacitor • 100nF capacitor The Max7219 is a 8-digit LED display driver, meaning it can drive up to 8 digits.
