Tetrapods Tetrapods Tetrapods!
It seems that tetrapods are generating quite a bit of interest, so here are a few links to tetrapod-related sites in Japanese:
Wooden tetrapods: make your own!
And concrete mini-tetrapods: make your own!
A bizarre video presented by Kuro and Toro (strange 3D-rendered cats with puddings for heads) about Ken Oyama, the tetrapod guy written about in my first tetrapod post:Vodpod videos no longer available.
And an Amazon link to all the books authored by Ken Oyama (although disappointingly no tetrapod books as yet).
A selection of YouTube videos.
And flickr has over 70 photos.
And finally, an incredibly lovely rotating tetrapod avatar.
