Adobe Flash on

Adobe Flash is Deprecated, EOL in 2020.

Sad, as, starting from around 2004, most of this sites
interactive web pages, video and audio content was made in Flash.

A petition to turn Flash into an open-source project is under way (2019).
So far, unsuccessful, but I am sure that it will eventually be possible
to get Adobe webpage emulators that can run Flash pages (after 2020).

Anyway, Flash material is now removed
and replaced with HTML5 on this website.

Except on a few pages that you can access through the links below
(Given the ''right'' browser, with Flash installed):
