Curvices is a mobile application by Rozalie Hirs (music, poetry, voice), Cox & Grusenmeyer (design, animation), Yvan vander Sanden (software design, realisation) and Machiel Spaan (spacial design) that accompanies you on your walk through Klankenbos. By changing location you codetermine the development of the music and the poetry. Where are you? What do you hear? Is it indigenous birds that are singing in the forest or do you hear birds from Portugal through your cell phone? Is it a siren you hear or is it the wind? By exploring the terrain you probe sounds and words, you make a journey through the forest, around the world, in as many steps as you like.
