although today fractal are used commonly in graphics design, television and any graphics interpretation, seeing spectacular images from http://ziza.ru/2006/05/24/otlichnaya-podborka.html, this image in particular still takes my attention for using in a very good way a fractal sensation
(please see the original image, there you can appreciate what I mean).
I don’t know which tool the artist used however you can do interesting artwork with: ultra fractal (shareware) and with povray also (but this last program is not fractal oriented as the first one and it uses a script language).
