Yesterday, I asked for subject requests for blog topics. I tend to stick to fandom-stuff, fic & other ramblings, so a lot of this is newer territory for me.
venturous asked me, "Why is your icon a spider?"
When I started this account (well, the LJ version of it, anyway) I wanted an icon that people would see and think of me, and I wanted it to be something that related to me, fandom, or ideally, both.
My original default was

I thought the lightning looked a bit like a spell being cast, and I love thunderstorms.
When I joined the exodus to IJ, and found I had 100 icons with my free account, compared to 15 with my advertising-sponsored account over
there... I started looking around for other icons that could represent "me" (and a whole lot of fandom ones, too).
I'd read a fic - I think by
rakina where Snape's animagus form was a large, black spider, and started looking for pictures of spiders. Gotta love Google Image Search...
That's when I found this one (my current default). I teach biology, and while I didn't take a course in arachnids, I did take entomology, and enjoyed learning about the critters. So - it still works as fandom-based & representative of me, in a way.
The other spider icon, my red-kneed tarantula, was my attempt at a Christmas-version of my icon. I'm not really talented with photoshop, so adding a Santa hat or tinsel to the black spider was a bit out of my realm of expertise, so I decided to search for a red (or green) spider. The result, was this:

. Who else but me would have a spider as a Christmas icon??
