This is the site you’re on now. The reason it is listed here now is that we completely redesigned it in 2016. Twice. We replaced a multi-page site with a single-page one for a while, and then expanded back to a new multi-page design again.
We made all the changes on the live copy of our site, and only put it into maintenance mode for a few hours. We kept discretely updating images and text when the site was back online again.
And we also designed a new logo for ourselves, added a blog, and translated the site into several languages.
