Hey, I have something useful to say for once! :)
Take the missile velocity, that's one vector. Then take the distance from
the missile to its target, that's another vector. Take their cross
product, i.e. y1*x2 - y2*x1. If it's negative, you turn one way, if it's
positive you turn the other (I forget which is which, but it should be
easy to figure out). I did this in a Palm game once and it looks cool...
