A painting from the 17th century can afford to look dated. Audiences are not so kind when viewing contemporary art by living artists. The fresh 'new look' always has value. Hot new work by young artists, or brand new twists in new works by established artists, have the look or appearance of information. New technologies are great for achieving the 'new look' and for creating the 'look of information', whether or not the work achieves value as information.
Appearance is a territory.
Audiences are exposed to the newest, most informed work, and they verify through their excitement and energy if the work is charged with information value. The new look can never be predictable. Information is always a perception and an experience of difference. It must come as a surprise. The most unlikely things slam together to become information.
