The design of the light screen is inspired by aquatic plant life. The light screen emulates the essence of the under water world by its organic form and spatial characteristics. Just as  oceanic plant life defines smaller spaces within the ocean, the light screen introduces a new way of vertical or horizontal space boundary that does not necessarily break the visual and acoustical connections between the spaces but gives a translucent characteristic to the boundary. The design of the module was started from a single hexagon. The hexagon has been selected because it is a  very well known form for modules, i.e. honeycomb. Since the honeycomb formation is widely used in modular designs, its pattern can be easily picked up by the viewer. This would be harmful to one of the major design goals which was to give the assembly an organic look. The form of the final unit is created by adding the four smaller hexagons. By doing so I gain the freedom to work within a larger boundary and worry less about the connection at every single hexagon’s boundary. It also provides more options for designing the unit within the defined boundary.

Layout A is the repetition of the unit without changing its rotation angle. The overall pattern can be rotated and used at any angle desired. The assembly of layout A is very easy and straight forward; it can reduce the complications that can arise during the erection of the piece.  On the other hand, because of the repetition of the same unit with the same rotation over and over again, the modular nature of the piece is clearly visible which is undesired according to the primary design goals.

In layout B the units have been put together with all three rotations that the module allows. This method allows for more variety in the overall screen and has more a organic characteristic. The rotations can be used to control the light transmitted through the screen. The texture variety also allows manipulation of the layout to emphasize the space at certain points.

The 3D model is developed with Rhinoceros 4.0. One module was 3D printed to create a rubber mold for multiple castings. The steps are as follows:

  1. A wooden box big enough to contain the printed unit is made.
  2. Half of the box is filled with clay and rubber is poured into the other half.
  3. The clay is removed and another batch of rubber is poured into the resulting cavity
  4. Release agent is the brushed onto the mold to ensure ease of extraction.
  5. The HYDRO-CAL® mix is poured into the mold through holes in the wooden box.
  6. Extract the HYDRO-CAL® unit from the mold and repeat steps 4-6.
