Lighting geometric design created with #OpenSCAD by @samakanbour.

I really love these beautifully designed candle containers that diffuse light through their holes. Useful, useable and desirable, these objects are mass-produced around the world. I can easily imagine consumers personalizing and purchasing them to decorate their homes and offices. Inspired by the Freshfiber lighting collection, I tried to capture a triangular geometric design, and generate different versions by playing with its parameters. I am pleased with the simplicity and depth of the designs, but I am not entirely satisfied with their limited variations. I would have loved having other than triangular shapes, such as circular or cubic.
