Joseph Nechvatal : Edmond Couchot Virus Attack Portrait 2005 is from Joseph Nechvatal's Computer Virus Project 2.0 series. This work follows along the same lines as previous viral works by Nechvatal from 1992 - works where an unpredictable progressive virus operates on a degradation/transformation of an image. Using a C++ framework, Joseph Nechvatal and his programmer/collaborator Stephane Sikora have brought Nechvatal's early computer virus project into the realm of artificial life (A-Life) (i.e. into a synthetic system that exhibits behaviors characteristic of natural living systems).
