A simulation of an installation may proceed the actual emulation in order to compare a (planned) emulation of the work to its 'original' state. Making a simulation includes: description of the behaviors and 'look and feel' of all (media) elements; digitization of non-digitized media elements; creating a simulation; reality check, i.e. compare simulation with the 'original' state of the installation.
