What started as a simple update of my website has finally become a project that I have worked on intermittently for 2 months. Texts were adapted and updated, the site restructured, many photos replaced. And especially made the website responsive, so that everyone on all media can see which collection I have and possibly learn something from it. In that sense, my site is also a kind of reference ‘book’. And as far as I know the only one. Of course I would like feedback. Don't spare me, send your valued comment to firstname.lastname@example.org.
