Terry, Some time ago I did a short clip 'after chegall', but this was pre Chaoscope. I wrote the program (using BBC BASIC for Window) for the 2D form and coloring of the individual frames and then did some post processing of the clip in Magix MEP. [http://www.zippyvideos.com/1259044453790716/test2/] I've been experimenting with Chaoscope, or more specifically using Ani4Chaoscope. I like what can be done (thrilled!) but so often, despite having SO carefully moved sliders to pick great starts and finishes, end up with a frame sequences with great gaps showing only a few dots or a single line. Nicolas, Loved your animation example, thanks. Is there a way to capture as video other than using some sort of repetitive screen grabbing utility? I've tried a few but they are more suited to recording mouse movements and window dragging for training videos -- no where near the speed to match your animation.
