Rooftoptiger is an artists' collective that builds participatory and performative installations in public spaces. The installations are site-specific creations. By intervening in a context, they try to entice people to take action as playful and critical designers of their own neighbourhood. The installations are built from recycled and local materials from the neighbourhood of the temporarily occupied sites.

The Rooftoptiger crew is a constantly changing group of artists, performers, poets, thinkers and ingenious craftspeople. They are nationally and internationally renowned for their own artistic practices. They are the initiators of Archipel.
