I've used to create a zooming starfi eld effect. Radial Blur and
Glow have been added to enhance the effect (Fig. 16.52).

As I mentioned, I really don't use Particle Playground all that
much. But when I do use it, I'm usually after the Wall proper-
ties. They allow you to create a mask on the layer and use it to
defl ect particles. It is so easy to set up and use to create spectac-
ular results, such as those you see in comp #6, Wall Tornado. In
this comp, I've created a tornado-shaped mask. Then, I change
the Wall>Boundary value to the mask I created. Once you do that
simple step, the particles bounce off the sides of the mask, and in
this case, create a really cool swirling effect. Note that the mask
must be on the same layer that Particle Playground is applied for
the effect to see and use it (Fig. 16.53).
