John Hanhardt describes in his essay on Nam June Paik’s TV Garden characteristic elements for the look and feel of this installation. For the Variable Media Approach the involvement of artists or their assistants is essential for determining ‘how to effectively reconstruct the experience’ (look and feel) of the work of art. ‘Among the specific issues discussed were how to preserve the look of the original television sets, the ratio of televisions to plants, the shape and size of the display, and the conditions of lighting and sound amplification.’ (p) Hanhardt, 2003, p. 74

The concept of 'look ' is connected to the practice of emulation (re-creation of the appearance of the original). With reference to Gonzales-Torres's Untitled, Nancy Spector says that "what is problematic is that if you replace a component of the work with something because it looks the same, the meaning might shift; or inveresely, choosing new material that can serve the same purpose as the original one, but looks utterly different, could be a gross misinterpretation of the look of the work". Spector, 2003, p. 98

Although the selection of a medium format and, by implication, its display eguipment has considerable effects on the quality and characteristics of the image, and thus playing a crucial a role in the slinking changes of our vision, is this matter increasingly pushed into the background in relation to installing art. Its consequence for the conservation and restoration of the information is so prominent and fundamental that too often the issue of display devices, and therefore the work as a totality and its re-installation, is being neglected.
