Faced with choosing people out of my 200+ friends list, I just generated some random numbers and picked that way. I did ten before I ran out of steam. I didn't really make a huge effort to make them lovely and nice -- I thought that would defeat the point of the exercise.
Two things: please don't feel obliged to actually use this icon and please don't feel obliged to credit me for destroying your nice icon with a badly done hat.
Oh, and I think LJ is still screwing up some user icons, so maybe the one I picked for you wasn't even yours in the first place. That would be funny.
I had to change the color a bit to make the hat show up on the right side, so I Xmas-ified the text as well.
