Okay, I took so long cos I've been trying to find the original--but yeah, all the xmas stuff, which you correctly ID'd, was put in by Coell at deck_the_icons. The swirly thing is trails of fire--I'm spinning poi. If you want, I could email you a link to a bigger version of the pic. :D
I've been kinda meaning to go back to my plain default icon, with holidaze being over, but some people have mentioned really liking the snow. :P
