I got to use a real Magic Cap, one of the examples of alternative metaphors, in the article, a black and white view of a room with a desk full of old office oddities. It was the worst user interface that may have ever been designed, like an Alice In Wonderland nightmare. Click an envelope on a desk or a clock, and it starts some other metaphor like an image of a spreadsheet in a dialog, or something, which might appeal to some kind of “grand adventure” logic, but in today’s context…I’ll avoid ending with a negative comment.
