How can a word appear or disappear? You can open and close a book; you can use a pencil and an eraser; you can use a keyboard or touch a screen. By moving your hand in front of the Desparecen Primero las Palabras display, a feast of red letters will glow to form a poem.

Desparecen Primero las Palabras (“First, The Words Disappear”) combines 160 infrared sensors and 160 alphanumeric LED displays to generate an interactive poem:

Desaparecen primero las palabras-cantándose así mismas en su mejor aspecto dan locura-gri-llos frotando alas-vivo lucha descarnada y llegan-impertinentes cabras-probar mi mano.

The installation, by Thomas Charveriat and Miriam Llorens, is part of Art Futura, October 27th-30th, Barcelona, Spain.
