At the very least, it's a great way to weed out anyone who doesn't like purple.
Click on 'About OKCupid' in the bottom right corner and then scroll all the way down and there'll be a bunch of 'Free Online Dating' options right at the bottom. Clicking on any of those (except the sexuality ones for some reason, but you don't want to date a lesbian anyway) brings up the search and you can browse to your heart's content from there.
Stalk your prey, Retro.
