your post is in the ask the author- part of the forum, but since it's not really a question for Ilona I will move it soonish.
I think you are talking about the chibis Ilona and Gordon are using on their blog? The little pictures that are both in the header of the post and also in the answers to the comments?
They were designed by a fan for Ilona and Gordon and are truly awesome. I will try to find the blog post Ilona made when they got the chibis, but not sure if I will find it, since the search function got disabled with a new design, I think.
