GNI_D_GH_86_SEP2004 is one of Ervinck’s first computer-generated drawings. This drawing gives a peep-in in a room filled with an object originating from Ervinck’s imagination. This drawing is of crucial importance in Ervinck’s oeuvre, as it indicates a mental shift: this is the first computer-generated drawing which hasn’t been (and which did not need to be) realised in the physical world.
