Thank you for the tips, Claudiomil and Falconperigot. I REALLY appreciate them. I had never thought about using anything other than the PE for the effect -- I really like your suggestion Falconperigot! Very cool! Using a spline object for a the effect will be easier to manage than a PE, especially since I am doing a looping animation. Thanks again, gents. You rule the pool. Isn't that ironic, all things considered? ;)
