Elco asked for a video of it in action on the shiftPWM thread, so here it is again on my thread:
This is the Bad Apple video scaled to 16x16 monochrome at 15fps/32 brightness levels 50Hz.
The flickering is a camera artifact and is not present looking at the display.
Hey Zuluriney, I thought you might see this. 
I am using processing to do my scaling and sending. I am not confident enough with C yet and there was a video library with examples that I could hack. So far I am really happy with the output. I will be checking out your thread too
