@Ghislaine, apologies I don't speak French, but I got Google to translate for me, which says "It's all well and good, but you have to comment on your filter when you put it here", if Google got it right. So, apologies once again - I didn't realise that we were supposed to do that, it seems many do not bother. But, anyway, here goes...

This filter is designed just to produce basic representations of the golden ratio and gives the user some control over how to do that.

It is also possible to create some interesting effects with the in-fill ellipses and with making the arcs and ellipses break out of their bounding.

The script contains a few elements that may be useful for other filter designers - there are functions to control random or sequential colouring of objects and functions that create squares, circles and ellipses.
