Controlling multiple RGB LEDs

Question

I'm working on a project that requires quite a few RGB LEDs. I would like to have two 5x6 grids (total of 30 LEDs per grid).

I need to acces each LED individually. Is there a special IC or a certain software trick I could use to that would help me with this project?
Thanks

I have not used this with the Arduion, but have used it in may other projects. But the MAX7300 (I2C) or the MAX7301 (SPI), coupled with some ULN2003 if needed and drive 28 more I/O ports. It's called a Bus Expander, It can be configured as an input or output. NXT also has some port expander IC's that can do the came thing.
