Porn, of the beastiality kind. The domain name use to belong to an Italian humor site (at least I think that's what it was; can't read the language, ya know). The image I had in my sig was of Tweedle-dee and Tweedle-dum standing with their arms around each other's shoulders, flanked by the name incandenza. The graphic can still be found on a Google image search of the name.
