I've written a small Windows programm for quick generation of 8x8 led matrix code.
Feel free to use this in any way you want.
.net 4.5 is required on the windows side.
MaxMatrix.h is required on the Arduino side.
example:
#include <MaxMatrix.h>
#include <avr/pgmspace.h>
byte smiley[] = {8, 8, B00111100, B01000010, B10010101, B10100001, B10100001, B10010101, B01000010, B00111100};
m.writeSprite(0, 0, smiley);
