+
+This fork has added example code for a 16x8 LED matrix.  In doing so, two additional python files were added:
+ex_16x8_pixels.py
+Adafruit_16x8.py
+
+These files can be used to demonstrate using a 16x8 LED matrix, such as [item # 2054 available at Adafruit.com.](http://www.adafruit.com/products/2054)
