The unit itself is a three paneled tetrahedron that can transform between open and closed positions. A steel frame and webbing system navigates the two languages of the complex grid of the units and rectangular extents of the system, allowing it to be deployed easily as retrofit.


The Tetriris system functional as both a ground and ceiling. The system provides an engaging experience for users while also collecting useful information for operators. Pedestrians can walk upon the glass surface, triggering pressure sensors the actuate the corresponding panels below. This produces a dramatic lighting effect while engaging users both below and above, in addition to spectacle of the unit itself.
