If you want simple, easy-to-see proof that astrology actually does have an affect, you need look no further than Astrofaces, one of the first astrological web sites that really grabbed my attention.
Astrofaces is trying to compile a collection of photographs of people's faces, sorting them by Sun/Moon/Rising sign, and letting the results speak for themselves.

It's quite another thing, though, to have visible proof staring you in the face that yes, astrology works. And it's quite the kick introducing your friendly neighborhood skeptic to have a browse.
Have a look at other people with your Sun Moon and Rising signs. Even if you're used to the notion, it can be a little startling at first.
