I don't know if Jun did the artwork or someone else, but the Halloween-themed Aikido kanji make me smile every time I look. All three are great, but I especially like the cat and its tail making the (don't know the shodo term) upward stroke on the bottom right. Sometimes I feel really serious on here, and I believe that's good, but I enjoy comic relief. The whole layout scheme of this message board tends lack any sort of "bubbliness." I think that's a good thing because it keeps me mindful of what I write. To the powers and webmasters at be, you have a decade of gratitude from me!
