tgarden originated in a partnership between foam in brussels and sponge in san francisco. the project resulted in a responsive play space whose visitors shape the media environment around them through their movement, gesture and social interaction. tgarden was developed in collaboration with several art and technology centers (in 2001 these were: the topological media lab at georgia institute of technology, ars electronica, v2, banff centre for the arts) and a number of independent artists, technologists and scientists from europe, usa and australia. essentially the tgarden (with t signifying 'time' and 'topology') constituted a built space in which the movements of the visitors' bodies was used by the tgarden's nervous system (hardware and software network) to shape visual, aural and tactile media. the gestures, such as those of touching, brushing along other bodies, dancing, stretching and falling, provided the impetus for the generative processes in tgarden.
