I used to call my special interests 'obsessions' back before I knew anything about autism. I have had obsessions for as long as I can recall. Generally I just keep that stuff to myself since no one ever really gets into the things I get into... I tend to bore the hell out of people
Right now I am in the process of slipping back into full blown drawing mode. I am also apparently leaning away from online/digital drawing and going back to those ultra fine point pens. The site I where I used to draw a lot changed and I dislike the changes... the zoom option sucks now and thats annoying since I go detail heavy. I'm back into the zentangle thing now and away from bizarro/abstract people. Though I do stick abstract type people/body parts into the zentangle stuff. Oddly enough, as obsessed with drawing as I get, I rarely get into art history or artists... except Hakuchi. He is frickin amazing and I heart his stuff so much.
I often enough get obsessed with religions. For awhile I was into voudon, voodoo, and candomble to a lesser extent. Sometimes I get obsessed with similarities in old school gods (ie sun and grain gods) and how that all plays out in more modern religion, namely the big three monotheistic ones. Most recently though I got obsessed with the Tao Teh ching and the Principia Discordia. Oddly enough I find those two to jive really well with the book of Ecclesiastes in the christian bible... and each other. I get into numerology as well.. not religious, but I got into it while going full blown Wicca obsessed, specifically nroogd. The numerology obsession quickly took over and stopped the wiccan thing for me. I freakin love numbers...
I also tend to get obsessed with songs and play them over and over. Sometimes one song will nudge me to getting obsessed with a singer/band which nudges me to get obsessed with any and everything else they have done. Most recent music obsession was with Godforbid of That Handsome Devil. That led me to getting obsessed with American Style Cardboard... Godforbid's and Doc Delay. Alaskan Fishermen (a band with Godforbid) was okay... but that stuff he did with Doc Delay is like an eargasm to me. I got into Les Claypool like that awhile back as well and went all out obsessed over Of Fungi and Foe. Lulz the Mushroom Men song... heh.
I have been obsessed with genealogy, pythons, russian blues, people, sexuality, interpersonal communication, nail art, gender bending and androgyny, myself, autism, making beaded jewelry, crocheting, sewing stuffed animals, painting barbies to look like day of the dead dolls, the list goes on and on...
Anyhoo... yeah, I do have my fair share as well.
