Light filter was an exploration of 3D printing as a tool for creating tailored, performative building materials.  It looked at how specific and highly controllable changes in geometry, made economically and technically possible by new technologies in manufacturing like 3D printing, could be leveraged to created performative building materials.  In this case the focus was on how varied light tubes could be designed to interact with the movement of the sun, providing unique control over the penetration of light into a space throughout the day.
