Making fountain bottom work

I hope this isn't the dumbest question in the world, and I have tried search but have only found basic answers on rotating textures, but I'm making a fountain. I finally managed to get the upper part, a torus, have the right animated texture with the water flowing down. That works. The bottom part, the pool, is a square prim. Is there any possibility to get the texture animated that it looks like it's flowing from the middle of the square outwards? Right now it just flows from one side to the other. Which parameters should I change? I just use the normal texture animation script.

I don't think it's possible with a standard cube prim and the smooth sliding animation. You could use a frame animation but it wouldn't be the same (choppy look). Using a torus flattened along the X axis (it's height, when initially rezzed) and the smooth sliding animation gives an inward or outward flow depending on the angle used.

Ah, thank you- so I'll use a torus then - it works with a normal one, so I should be able to make it work with a flattened one too. I think frame anim would be too much flickering anyway.

You can use llSetTextureAnim(SCALE, . . .) but I do not know how easy it is to get it smooth. I played with that for a while then went a different direction.
