Indeed, there is an internet browser called Vivaldi that was made by an Icelandic organization established by Jon Stephenson von Tetzchner, who is a previous President of Show Programming. While the organizer is Icelandic, Vivaldi Innovations, the organization behind the Vivaldi program, has a huge presence in Norway, and the actual program is known for its customization choices and elements. It's not explicitly an Italian-created program, but rather it has an European beginning.
