It consists of three wooden pinhole cameras intalled in an iron frame in a scale of 1:2:20 (according to the ratio between the area of Kowloon, Hong Kong and the New Territories.) On each camera, letters of mirror, HEUNG GONG, GAU LONG and SUN GAI which are cantonese prounciations of Hong Kon, Kowloon and the New Territories respectively, are separately inlaid on the front. Interestingly, not many local Chinese could pronounce or recognize them.

The inner back wall was coated with Liquid Light (a light-sensitive material). Then each camera was exposed in the Central of Hong Kong, Tsim Sha Tsui of Kowloon or Kam Tin of the New Territories separately (where one can find the old supreme court, the old clock tower or the historic castle that are among the most strongly promoted by the Hong Kong Tourist Association as cultural heritage.) During the exposure, a video documentation of the site was made. Three videos displayed together (consecutively and simultaneously in three TV sets) constitute the work Visitor's Guide.

After collecting the images of the three different places, VIS(I)TA is displayed to audience in an indoor environment. Only by standing in front of the camera, the viewer's image will be superimposed with the images of different places at one time. However, these images are never seen by eyes even though they are real. Audience are encouraged to "see" the images in their mind with the reference to Visitor's Guide.
