Real fun One Pager for product designer Erd Yakingun in the form of a vintage operating system. Lovely touch with the restart menu item, as well with the About window (containing the site credits) when clicking the top left system icon.

This website has unfortunately been redesigned or gone offline, so I have removed the direct link to it. The screenshot below hopefully preserved enough of the design but if you are really keen to inspect further, try this link. FYI: the site was first featured on 13 March 2020.
