I find Fractal Explorer to be my program of choice in that it is not only free (so that you can take your time in playing with/learning fractals) but that it is fairly easy to learn. If you can pay for it, UltraFractal is pretty nice as well, but, I found the interface to be a tad more difficult then FE... My Fractal Galleries, FYI: http://jamesrskemp.net/jms1fractalgalleries.htm There are some good ones, but some okay ones as well... ~james
