The Rainbowduino can be use to drive 8×8 RGB Led Matrices or a 4x4x4 RGB LED Cube in common Anode mode. Its a nice board for practicing some programming skills, in particular loops. The example below shows some randomised colors
Here is a picture of the shield fitted to an Arduino board and also there is an 8×8 matrix fitted to the shield, you usually buy these seperately

#include <Rainbowduino.h>
void setup()
{
Rb.init();
}
unsigned char x,y,z;
void loop()
{
//fill ever led in the matrix
for(x=0;x<8;x++)
{
for(y=0;y<8;y++)
{
//RANDOM COLOR
Rb.setPixelXY(x,y,random(0xFF),random(0xFF),random(0xFF)); //uses R, G and B bytes
}
}
//delay for 2 seconds
delay(2000);
}
