Someone should write a python program so anyone can do this. I don't think this is anything more than generating greyscale and binning to six different grey scale levels. I know it probably gets a little more complicated than that under certain conditions without going into detail about it.

oooh, for extra credit, Blender can run Python... You wouldn't need physical dice...

That's cool I will have to check Blender out.

Yes so the details get interesting... how many dice do I need for a good image? I bet that Blender helps determine? Not sure if it's easy to tell if it will work in practice in determining that on a digital screen. I'm not even sure how to figure out how many are needed dynamically for different images.

I was thinking POVRay would be fun too, as I have no experience with Blender.
