Yup I could most likely do it with the % operator. I'm still new to openSCAd
so I just chose a way and decided to stick with it until either it worked or
I decided it couldn't be done. 

I put my code up on thingiverse (http://www.thingiverse.com/thing:779394)
because the end result of it is meant to be a 3D printed object. Anybody
interested in what I did should take a look.

I will look into the modulo 256 stuff next. Maybe I'll redo it all and end
up with a much shorter listing. 

thanks again...
