Cherryman has the answer: your materials are set to "world standard", this means that the origin of the material is computed at the origin of the world, always. So when your figure moves, the material looks animated, because the distance of the figure from the center of the world has changed. If you had used "object standard" instead, the materials would have used the center of the figure to compute the material's origin, and they would've been consistant.
But it suits the mood a lot better in world standard imho.
