LOOKING FOR SCRIPT HELP!! Animated Texture

[Gloverflo]

I have a spider that is single prim, I'm trying to make it appear that it is walking and having trouble with the  Animated Textures.

In other words, 

 I have a spider, its a single prim, no extra linksets. I'm trying to do a single prim alpha animation with its legs, to make it appear like its walking? If that makes sense? like old school breedables. Cant seem to figure it out, any suggestions?

Looks to me like it might be using some sort of sculpty model swapping?

There are better animation techniques now like animesh.
