Do you ever get fond of icons used by people on your friends list? Every once in a while, a friend of mine will have an icon that I start to think of, whenever I think of that person. With crackferret, it was her black and white ferret picture--it was so cute! With snowelf, it was a blue-shaded picture of a girl that I imagined was what Snowelf really looks like, though I'm sure that's not so. With nixnivis, it's all of her 'brain in a jar' icons; with morsefan, it's her icon of the elderly gentleman. With cpsingsforhim, it's her Elijah Wood icon. And with caersidi, it's her icon made from John Williams Waterhouse's painting The Crystal Ball. There are lots of others, but that's enough to give you the idea.
Somehow, I come to associate particular icons more strongly with the people behind them than others. For qos, for example, the icon of the woman holding the sword is it, quintessentially her. For shusu, it's her red one. Both of these people have various other icons, but those are the ones I most strongly associate with those two people.
Does anyone else experience this phenomenon? Do you have favorites among your friends' icons, and do you miss them when they're gone and wish you'd copied the graphic?
