I don't understand. This is just the thing that makes sin or cos a
reasonable choice, I thought. 
I'm obviously missing something very important here. The only thing that
I have to support my choice is a working animation that does what it
should do for me, but, admittedly, is probably not what a hardcore
pov-er would consider realistic.
