Polycat
Polycat and Catya.org are the only two that I designed just for me, without taking anyone else's tastes into account.
When I was looking for a theme for Polycat I fell in love with this one because of the eyes, for two reasons. First, I think Polyamory is best done eyes-wide-open. Second, at the time i was building the site anonymously (long story), and the fact that it was ONLY the eyes, and not MY eyes, felt very much like the right thing.
Other than the theme, it's all text, and designed to be expandable and easily have more added to it. Sadly, this site attracts a TON of spam.
