There's the Interface Hall of Shame and also the Interface Hall of Fame for desktop UI design. The company that created the site doesn't exist since quite a time. Their site has been archived by another company 23 years ago. Nevertheless it's still funny to browse through it and see what people do just because it can be done.
And if I may be a bit immodest: There's a comment from me on the Lotus Notes feedback page since then. (For the younger: No, that's not a sports car for bankers or musicians.)
Is there something comparable for web design?
Nothing is so useless that it cannot at least serve as a bad example.
