With architects of Vienna's Technical University and with their textile handicraft teacher, pupils of forms one to four create so-called "roomTubes" – from design to cutting to sowing with special sewing machines – and then discover new spaces for themselves. Many of them go and roam in their "roomTubes": 6 to 15 year old classmates, integration children with various impairments, students, also grown-ups, kindergarten children, exhibition visitors, sometimes even babies. Easily transportable, usable almost everywhere, the expandable shapes offer protection, change the spatio-social perception and facilitate new encounters.
