This is what the sign looks like in multi-color mode.
Here is the Video:
I can also do graphics on the LED sign. This is a picture of the logo that I uploaded as a BMP to the sign for display. I was looking for something with lots of color and with a black background. White backgrounds do not work very well as the white light blinds you! To display graphics I had to write a routine to rotate the bytes from horizontal to vertical orientation. Then I added an offset to make it scroll up. I should mention that this is running in 8 data line mode, the right side loops back to the next 8 rows on the left side to get up to 16 lines to display.
This is the video on YouTube.
Here are a couple of still shots of the sign displaying graphics.
