Waka [flickr][blog][youtube] – Another fabulous builder in Japan. He blogs about his creations, sometimes showing the details of their construction. Most of his MOCs are mecha or sci-fi, but he has some cool characters as well.
Zi Zy [flickr][blog] – One of my favorite mecha builders. His creations are intricate and steeped in anime sensibility. His blog is in Japanese. He has published a number of books on building, but they are difficult to get outside of Japan.
