Lava lamps are sooo cool. I've had a couple XD I could stare & watch~
but ya know a 質問 on "What organization should I GIVE to this year?" might seem a little less greedy. Greed & comercialism makes me sad-not that あなた are, I understand - I have asked for nothing (but cheese, lol), and I am not into much this クリスマス as far as gift buying either -like I usually am.
クリスマス isn't even about that "stuff" to me.
but in answer to your question: How about a funny winter hat? lol :D
