Geometria do Êxtase
(Geometry of Ecstasy), 1982.
In this poem we look straight down at the top surface of a cube. An invisible light source orbits the cube, casting verbal shadows that can be seen gyrating clockwise, much in the manner of a sundial. As new shadows are cast, the letters permutate to produce new words in multiple languages. The poem executes in a loop. Originally written in Basic, it was part of a series of experimental ASCII works that Kac created in the early 1980s.
