@takashichea: Well how very Scrooge of you to set up a Christmas profile contest and then not bother to do your own. I stick by what I said; for shame indeed! ;P
I might change the default images for fun on Christmas.
It would be a lot of effort just for one day. It would be better to do it now and change them back after Christmas. As long as someone keeps a list of characters to make it easy to find them and change them back, I see no problem with it :)
