Holopoetry and Fractal Holopoetry: Digital Holography as an Art Medium

In 1983 Eduardo Kac began researching the possibilities of holographic poetry, or holopoetry. This article briefly describes holopoems made between 1983 and 1988 and then focuses on the fractal holopoem Quando? (When?), co-authored with computer artist, Ormeo Botelho. The authors present the basic concepts of fractal geometry as a tool for the creation of holographic art and show how it was used for the elaboration of Quando? In a technical appendix, they describe the process of digitally synthesizing a fractal holopoem.
