For that file i have made absolutly nothing special out that I have described!
It was a new launch of Moi.
It's // DistortCurves v.0.9 - Max Smirnov. 2014
there is Rebuild inside

Will stay a mystery like the Voronoi in the past! ;)

PS I reload the file above: no problem! (before reload the new version 1)

PSS I see that is not the V 1 of the DisturbCurves : maybe that is that...
