On page 147, Figure 10 depicts a hologram "Adrift" (1991) by Kac that is acknowledged to be in the collection of the Sackner Archive. Kac writes on page 145, "Adrift is composed basically of seven words that dissolve in space and into each other as the viewer reads them. In one case, the reader may be invited to start reading from the letter which is further away from him or her. In another case, the letter closer to the reader could be the starting point. The letters that make the words are floating irregularly along several Z axes, except for the word 'breathe', which is integrated into the overall light field. This word is blown by an imaginary wind as its letters actually move away from their original position to dissolve the light field. The movement of the letters in this word disrupts the apparent stability of the other words." -- Source of annotation: Marvin or Ruth Sackner.
