What’s an avatar?
In Hindu mythology, an “avatar” was a particular incarnation of a deity. Nowadays, at least in techspeak, it’s more of a general embodiment or representation, usually of a perso.
My homepage has two avatars on it. The first is from “Designhergals” (www.designhergals.com), which lets you assemble a cartoon character from pieces, and then use that image on cards, stationary, and so on. It’s very nicely done, and really cute. Quite girly, too, but that’s the point.
This representation doesn’t really look a lot like me, but it’s not a bad idealization (considering the range of choices they offer).
The other is from Second Life, a 3D virtual-reality game. “Game” isn’t really the right term, as you don’t have to kill dragons or win wars. Second life is more about interpersonal interaction, building things, commerce, and so on. It’s very immersive, and you could spend a ton of time on it without really trying. My character in that world also isn’t terribly similar to how I look, but it’s difficult (possible, but difficult) to create a non-stereotypically-attractive avatar.
Interacting as a woman in SL is interesting. I’m not sure how many guys masquerade (for whatever purpose) in a female avatar, but as a girl you do tend to get a higher-than-average share of conversations, offers of help, and so on.
There are whole blogs just about SL, and my experience isn’t so deep (haven’t had a lot of time to sink into it, for fear of getting enveloped and suddenly losing large chunks of real life!
. So won’t say a lot more about it unless there’s some reason to write more later. [Addition - you can download SL and create a character for free. If you want to say that I referred you, my in-world name is "Robin Raffke". I get some bonus, but am not sure exactly what.]
