How do you create the effect in photoshop to make shapes appear to shoot **out** from the center of an image, a bit like light rays.

Radial blur with zoom seems to blur both out from the center *and* towards to the center (the effect you would see if you were moving in relation to an object). This is close but ultimately isn't the effect i'm after
