pin light question

I've seen several icons that use the pin light effect, which I think looks totally awesome. Only problem for me: I have PSP7, which, as far as I know doesn't have this effect. :( Is there any way to use other means to get this effect using PSP7? Or a similar effect. Thanks bunches!

EDIT: I found an example..

That's sort of the effect I'm looking for.
