DesignTO Festival 2019 - Polytope Exhibition

The Polytope exhibit is a part of the DesignTO Festival in Toronto, Canada and is the result of a design collaboration between David Lister and Daniel Gruetter. The exhibition runs from Sat, Jan 19, 2019 — Sun, Jan 27, 2019, and there will be an open reception on Thurs, Jan 24, 2019 at 117 Ossington Ave.

‘Polytope’ is a collection of pendant lights that synthesizes the material properties of brass alloy with the algorithmically assisted generation of tessellated forms and 3-axis CNC fabrication.

‘Polytope’ is named after the geometric category of flat sided shapes that exist in any number of dimensions. Initially these forms are created as digital 3D models, but in order to facilitate 3-axis CNC fabrication, they are ‘unfolded’ into two dimensions. After machining in this flat state, they are then folded by hand, transforming from two dimensions back to three dimensional polyhedra.

These tessellated forms are generated using rules for the division of space commonly seen in the natural world. Brass’ ductility enables these flat shapes to be folded and retain their shape. This process of plastic deformation allows the brass to be wrapped around a light source.


Integrating process, form, and material aptitude, Polytope engages with the geometry of the natural world to offer dynamic lighting opportunities.
