Media facades are a novel and emerging research domain that comes up with several challenges: crafting early interactive prototypes and exploring content, form variations and interactivity is still cumbersome, challenging and comes at high cost. The prototyping toolkit LightBricks is intended to build miniature models of low-resolution media facades and pre-test visual content. It helps design teams to explore media architecture, interactivity and lighting design rapidly and at low cost in early phases of the design process.
