Homeware company Ngispen have collaborated dutch designer Richard Hutten to develop ‘Thunderball’, a pendant light whose overall form is dictated by the user.

The light, which is constructed from of a flat sheet of metal is composed of a series of interlocking hexagons. Connecting each shape are small hinges that allow the user to form and fold the object in endless ways.
