riverIslandJohn Cayley’s work often employs a technique he calls “transliteral morphing.” This is a letter-by-letter morphing that transitions from one text to another, much as graphical morphing moves points in space so as to transition from one image to another. riverIsland is composed of two loops of poems, one horizontal and one vertical, and the reader can use on-screen arrows or QuicktimeVR movies in order to trigger movement along these loops. When the reader indicates that a move should be made from one poem to another, the appropriate transliteral morph is performed by the computer.
