Diatolumen is a lampshade model inspired by forms generated from the machine learning system, StyleGAN, using Runway software. Trained from 500 microscopic images of diatoms, the system generated new diatoms created with artificial intelligence, which were successively used as inspiration to create a 3D model of a lampshade, a symbolic object, chosen with the aim to illuminate our creativity towards a more active co-design between nature, technology, and humanity.
