[Το κείμενο διατίθεται μόνο στα Αγγλικά] Animata is an open-source software developped by Hungarian programmers and artists. http://animata.kibu.hu/
Originally used for puppet-animation, comes very handy for small-scale non-cubic improvisational mapping: we find a surface, possibly outdoors, and build up the set based on stills. Sample images >> http://loope.tv
