I really don't have a specific one, I don't think... my interests jump from thing to thing depending on my mood.
I like artsy type stuff, but don't really care about what others are doing with it, lol, I'm obsessed in my own mind about what I could create with whatever is lying in front of me-whether it be posterboard, facepaint, glue and beads, etc... it doesn't matter, I'll make use of it in some way.
The other thing, I suppose... is information about serial killers or as someone else mentioned, crime in general. I watch a lot of TruTV (formerly CourtTV) and enjoy it thoroughly... but stories about serial killers really get me curious. Maybe it's just the whole idea of "how could they get away with it for so long?" coupled with the fact that it's usually something super tiny that gets them caught... some of them are interesting because they make it a "puzzle" or "riddle" to catch them... things like that. I really dunno why I like those things so much... I just do.
