Hi Geoffrey,

Detecting 1x1 plates should not be hard if they pass close to fiber optic end to
efficiently block light.

I believe it's caused by the blue background I used that somewhat fooled my
camera white balance. That said there is a lot of light loss along the fiber -
These are not the high grade ones that transmit light for hundreds of km without
repeaters!!!

And many thanks for the original idea ;o)
