How do I make, inject, or find a moving texture for a skin?

Ive seen on several mods including greennc's cannabis island mod for example that in the walls of the map he has like a see-thrugh wall with like moving marijuana leaves moving in it and on some other maps ive seen like fire coming off a sword. I was just wondering how you got a texture to move like this so if anyone could help me out it would be greatly apprecitated... thanks!

An effect tag, that predefines where/what the "bitmap(s)" will do, or a model animation. Effects are used in grenade smoke, nuzzles, and other stuff that has moving bitmaps (besides something like the light bridge, or shields, those have moving bitmap scrolls)

Scrolling textures, like on the Halo ring, are defined in the shader_model tag.
