Res Ipsa is an compilation of works made by some kind of action shaping the filler once it is prepared inside the frame. The works thus function as a recording device and give a statement of the event taking place while the filler was still wet.

Res Ipsa is Latin for "the thing itself" and is part of the juridical term "Res ipsa loquitur" (the thing speaks for itself), used when an injury or accident in itself clearly shows who is responsible, such as an instrument left inside a body after surgery.
