The design for this prismatic shaped brick was inspired by origami. The faces of the bricks have a multi-faceted triangulated geometry which allows the light falling on it to reflect in a dynamic way.

A triangular grid was first formed on the surface to divide it in multiple triangles. These triangular faces were then distorted to give the brick a 3D prismatic pattern. Then the holes in the brick were introduced to let the light pass after much diffusion and diffraction.

The diagrams below explain the development of the design from the initial concept to the final geometry.

Various factors influenced the final design of the bricks, such as the limitations/ abilities of the machines, nature of the plaster used & de-moulding process.
