This site contrasts two different media tactics of approaching nothing:
Such media enlist the viewer as a meaning-making machine, in order to make the meaning of "nothing."
Although a limit of the semiotic system is indeed approached, the system itself necessarily remains intact and un-exceeded. The viewer resides within and functions to maintain the system. The system continues to function well enough to represent its inability to represent.
Such media looks "like" nothing, but "nothing" is not experienced.
