Actually, I was working on this very thing (45 degree angles) for a new GBC
module over the weekend.  (you remember GBC, don't you?  You know, the creature
that wouldn't die  :)  - thanks Steve for such a wonderful way to waste all my
free time  :)  ).

Using the double bend lift arms, you can achieve a 45 degree mount pretty
easily.  They may seem a little big at face value, but we are talking about
mounting them alongside a conveyor belt that moves 10x10x10 crates.  So, they
shouldn't seem too disproportionate.

That all being said, I still wonder if my idea about using a motor to turn
another motor that is connected to a polarity switch (detailed in a previous
post) would work.  Those Lego motors are awfully efficient.  I might just have
to try it at home tonight.  This would be the same cost (2 motors @ $15 each + 1
polarity switch @ $10) as the 4 polarity switch solution.  Plus, it would be a
little more elegant.
