LED Byte Generator

Simple little utility for generating byte codes for 8x8 LED matrices driven by the MAX7219/MAX7221 to use in code such as C/C++ or Energia and run on an Arduino, Raspberry Pi or micro controller such as the MSP430. Change history: Version 0.3 adds a ying-yang icon to toggle all LEDs. Version 0.2 now allows shifting of LEDs in all directions. This makes it much less work to animate scrolling.
