Hi all

Pilou, I hope you don't mind me introducing an free Online Tool here.

Stumbled across this free Online Tool, which may interest also
MOI Users, Graphic Designers because of Vectorgraphics.
(Results can be also saved as .SVG Vectorgraphic)

Its a kind of Halftone Generator.
You can use a Photo, choose between different Shapes and the space
between the Shapes and your Photo/Rendering would converted then
in a Halftone Picture. Which can also be saved as SVG.

Here the Link:
