@Pilou:

Maybe a cool explanation!
But want some proof of that!

else some italian curves
-----------------------------

That was just my deduction :) ..no proof...

about Italian curves:
..i don't want to start again the eternal discussion between you and us about who is best to make wine,cheese,fashion... :)

here an example of mathematic and design to create a new shape of pasta by one of the best Italian designers:Giorgetto Giugiaro !





This is also a quick introduction to Giugiaro,better known as car-designer
I'm just modeling his classic piece that i'll post soon here
Au revoir ;)
