All the recent developments with orbital rendering in Fractint - for which I say well done, beautiful, some pars from me to follow soon - also makes me think of another fractal type composed of curved lines, namely Klienian Groups, e.g. as at http://klein.math.okstate.edu/IndrasPearls/ It would be great to have these incorporated into Fractint. One suggestion - another dream of mine - would be to enlarge the L-systems possibilities to enable L-systems lines themselves to be curved, e.g. according to various user-input equations for curved lines such as the circle and parts of it, spirals, parabolae, hyperbolae, etc. THIS would in tself be a huge increase in the capabilities of Fractint's L-systems programming, whether or not it led to Kleinian groups being added to Fractint.
