Hi,
Here
http://www.mannes-tech.com/It/is "Mac OS X application for researchers in complex dynamical systems. It allows you to visualize complex functions under iteration, producing fractal images such as the famous Mandelbrot or Julia sets. It isn't limited to the Mandelbrot set, however. It lets you explore your own functions by writing code right inside the application. Your code is compiled on thScreenshote fly and lets you create arbitrary graphics."
I do not have Mac so I can't try it.
It is from 2012 soit is not new , but I found month a go.
What do you think about it ?
