Australian Centre for Contemporary Art — A small gallery with no permanent collection. “30 Second Text” is a room with a single light and text on the wall. It is a few paragraphs about a doctor who tried to communicate with a severed head of a deceased human. Apparently it blinked when its name was called, twice, then nothing on the third attempt, after about 30 seconds.
At the bottom it states that it should take you about 30 seconds to read the text. Then the light turns off and it is pitch black.
