Dear Fractinters, - sciwise: thanks for that interesting formula! - Gerald: thanks to make it work on my old laptop :). - JoT: ********* Well, I finally got it to work with tweax; it is one of the most interesting images I have seen, like with all the dots. However, there are no parameters to tweak so I can't do a morph animation, or as I was hoping, something that would model electricity thru a diode or something. Zooming in gets you nowhere fast; zooming out is ok for a few orders, then it STOPS at about E-005. You cant back out further - keep getting the same image. (I have seen this before. Strange) ********** Here is the same .frm with (Rs*p1). It maybe makes no sense but at least the "value" of Rs can be changed :) even on the complex plane :(. Cheers, Guy
