This prototype chaise is modelled in Rhino 3D. The "Quarter Iso Grid"- Cutting Files are generated by a grasshopper definition which is inspired by Mike Sheldrake's great iso grid cardboard surfboards. This prototype development is kindly supported by Mike Sheldrake (http://sheldrake.net/cardboards/), Oliver Fritz // CIAD - Cologne Institute for Architectural Design // Chair of CAD.CAM Tischlerei Bächer GmbH.
