"Outer-Art" is a movement set up as a protest against, or to ridicule, the random modern art which states that everything is… art!
It was initiated by Florentin Smarandache, in 1990s, who ironically called for an upside-down artwork: to do art in a way it is not supposed to be done, i.e. to make art as ugly, as silly, as wrong as possible, and generally as impossible as possible.
