READYMADE [fr. tout-fait]

A readymade is the observed invisible, which, in the very moment of observation transforms itself to another observed invisible matter.
A readymade is something which can be observed (or be visible) only under a very, very short time.
It is infra-thin matter.
To work with readymades, the artist has to work fast, and with a considerable precision.
Else it would make no or only insignificant difference.
