Spiral Line is a collection of parametric lamps, with different shapes that can be used to give an atmosphere to a space. Each one has its own personality and lighting characteristic, which can be used to accentuate a great range of spaces. Inspired on the shapes of the guaje pumpkin shells, these lamps give out an elegant lighting for any place. The program we created, by being parametric, allows a relatively flexible design process; this helps us while making variations on the shape and size of each lamp, giving us the opportunity to respond efficiently and on a rapid manner to special requests as well as making possible the manufacture of customized pieces.
