Most of animations are quite ugly because their authors can't see it without many hours of calculations. Ansver was negative for many years, since Mandelbrot set is very computational expensive. Thinks are changing. Today's computer are fast enought to calculate aprox. 1000 pixels per frame.
Several programs doing that are available.
But 30x30 animation still looks quite ugly. To make animation nice you need at least 320x200 pixels. One possibility is wait until computers will be fast enought, but it should take many years and then 320x200 animations will be obsolette and everyone will want 1024x768 resolution instead. There were some programs doing similiar trick before but we don't know about any able to do zooming interactivly in same or higher speed than XaoS does. Many other tricks was later implemented into XaoS to archieve higher framerate.
