Tierazon2 is one of my favourite freeware fractal generators.
www.eclectasy.com/Iterations-et-Flarium24/software/ Just scroll down to "tierazon2-06-exe.zip" to download the programme. Only 578kb to download.

If you would like to make flame fractals using freeware software you can download the Gimp for windows which has a flame plugin (I have a tutorial on how to use this at www.arcanefractals.com)

Also you can use Apophysis with the freeware fractal programme chaospro
