The document proposes an interactive sculpture called "Imaginary World" for the 2010 Shanghai World Expo. The sculpture is meant to provide visitors a moment of reflection and escape from busy urban life. It would use Priva-Lite glass that becomes transparent when sensors detect movement, revealing underwater images. This allows the sculpture to be a silent monument from the outside but to immerse viewers as they pass through with images of nature. The proposed materials are a metal frame with Priva-Lite glass panels and sensors on all sides to control separate images.

Concept and meaning front sculpture + lightning and images
People in cities are busy and loose contact with the beauty of nature. Imagi-
nary world gives within this world of being busy a moment of withdrawing,
harmony and dreaming. A moment for one self. Looking at the beauty of the
world down in the deepsea. Unspoiled nature. Silent beauty. Amazing. Imagi-
nary World combines nature and innovative technique.
Imaginary world is an interactive sculpture and has to be discovered. From
the outside and from far it is a silent monument. At the moment people get
in light and images are shown. Not very present but silent and polite images
as if they are living up in a dream. People can walk through the scuplture and
have a moment of reflection in the centre of the sculpture.
I am creating imaginary spaces because I am convinced people need every
day a moment for themselves, alone, of dreaming, of reflecting of nothing.

3. Material
Metal frame with priva-lite glass. The glass is diffuse. When a person passes a
sensor, the glass will become transparent for 2 minutes. Suddenly a new woldl
appears. After this two-minute moment the glass diffuses again.
Subject photographs
a world of transparant seagrass on the outside of the sculpture
inside the beautyiful but real deepsea world with transparent amazing
deepsea floating inhabitants
Positioning
Positioning in Bailianjing Park. The basis of the sculpture can be
either grass, wood or concrete.

4. Technique
SGG PRIVA-LITE®, “intelligent” glass
It takes an electrical sensor to make the transition from clear to translucent.
SGG PRIVA-LITE® allows you to see through the glass one moment and then
shields you the next.
SGG PRIVA-LITE®’s secret: the Liquid Crystals
It is a laminated glazing made of two sheets of extra clear glass and a liquid
crystal film. The current standard composition is +-12mm thick.
The polymer and the liquid crystals are encapsulated in the LC film of which
both faces are covered with a transparent, electrical conductive coating and
are connected to the power supply thanks to 2 flat electrical busbars
Composition of the liquid crystal (LC) films
When the glass is switched OFF from its special power supply, the liquid cry-
stals are randomly scattered and diffuse light in all directions.
In this state SGG PRIVA-LITE® is then translucent and prevents both sides
from seeing through the glass.
All the wall of the sculpture will be double layered with separate images and
sensors on every side.
Costs
Technical preparations and drawings € 7.500
Production and putting up
the sculpture in Shanghai all-in € 140.000
Standby budget € 5.000
Way of production
PRIVA-Lite is represented over the whole world also in the far east. Technical
preparations can be done in the Netherlands. Production locally.
