I have just tried the technique out, and I must say it is GREAT!!! I've even gotten it to look better in the compositor than it does in Gimp!

It's not. It's Unsharp Mask. It makes a blurred version of the image, and compares the blurred and the original image to find edges. It then increases contrast on those edges to get them to look sharper. It's called Unsharp Mask because it has to blur it to sharpen it.

I never quite understand why a sharpening filter is called 'unsharpen'…

KiZa: It's the Math node, set to Multiply. It's available in 2.43 :)

@Freakydude: Check BlenderArtists: http://blenderartists.org/forum/showthread.php?t=89067 and Search for Wireframe; scripts abound. Enjoy!

Hey, Matt or anyone, could you tell me please what is that node between Substract and RGB Curves, used to "tweak the mask strength across different areas"? :P thx. FreakyDude, I'm sorry I don't know about how you can do that…

well there's a lot you can do with it I suppose, but does anyone knows how to use the node editor to make WIREFRAME settings work? It's something I'm trying to get correct without having to use edge in the render options (doesn't do exactly what I want) or duplicate the mesh(which seems a cheap and sloppy trick for the sake of creating a material option).
But as of yet I haven't been able to do that with nodes. Or rather haven't figured out how to do that with nodes.

[quote]What caught my eye here is that the compositor is already becoming powerful enough to achieve such specific results.[/quote]
Yes that is true – really fascinating… One should found a research group that plays with the compositor for some weeks to find out how powerful it is
