In fact my very first steps with Filter Effects.
Using aboundantly the "Melt" effect bundled in the development version. That's one of the reason they are a little bit heavy. I systematically removed its Convolve Matrix Primitive and reduced the blur to nearly zero.
Another one used also to build them was "Inkbleed".
DON'T BE WORRY if at the moment, the navigators are unable to display correctly most of my filters. Inkscape display them nicely and export them as you see here. My first wish while creating these filters is to improve Inkscape illustration capabilities.
