Not that I have any real expertise in the subject matter, but I've seen
enough people not mention it that I thought I should...

I doubt your eye stays perfectly still while the whole scanning operation
is going on.  A stalled scanner could possibly damage more than "one
pixel area", just because your eye will be bobbing around a bit.  I'd
also be concerned with a stalled scanner damaging cells deeper in.
i.e. assume we've eaten through a number of rods&cones on the surface,
what's behind that?  Nerve tissue for other rods&cones?  No thanks.

As an aside, anyone know how to configure GCC for a Harvard architecture
processor (i.e. PIC, 8051, etc...) ?
