Disappear: Abracadabra!
Alakazam. Presto chango. Treguna Mekoides Trecorum Satis Dee. Shazam. In canis corpore transmuto. Open sesame.
Interfacial #1: Hi Hi Hi HiHi
It's difficult to imagine a text one needs to pay more attention to than this one. There's a sleight of hand an author performs when writing. Pay attention, in magical words, for an abracadabra moment: the text will disappear. The interface is interequitable for an author, allowing an author the power to frustrate a reader with a refresh button. An audience might be said to be coerced to read more attentively, to remember what happened previously since getting back to appearing means trying to find where one was before.
Interfacial #2: Bye Bye Bye ByeBye
Sure there are ways to game this with screenshots and copy/pastes, but for an audience that's pretty irritating. At the very "least" this interface might make an audience, Abracadabra, disappear.
