Well, first you'll have to have your eyes surgically altered to 6" on
center.  ;)

If you violate the rule, you'll get too much on-film deviation, and
the slide will be difficult or impossible to view. Trust me! Or, don't
and try it yourself - that's the best way to convince yourself that
it shouldn't be done. A _little_ violation of the 1/30 rule may only
make the slide difficult to view, or give a little eyestrain.
