Hi Marco

>>Are you running for a prize ? :)
>>It seems that this Voronoi plugin is a sort of personal challenge for you.
No, it's not a challenge. I just want to make a good script and then forget about it.

>>I did some test but I can't figure out how the new "Filter" affects the output of the Voronoi.
It doesn't affects the output if Corners slider set to 0. Set corners to 100 and the move the Filter slider.
