D-tower, Doetinchem

D-tower is a 12 m tall tower designed by artist Q.S. Serafijn and architect Lars Spuybroek / NOX, and is located in the city of Doetinchem, Netherlands, mapping the emotions of the inhabitants. By combining network relationships with a performative sculpture, the project locates itself as both a prefabricated epoxy sculpture in the city and a performative entity affected by the inhabitants.


How it performs:
The tower changes the lights according to emotions reflected from the D-tower website, ( On the website there is a questionnaire, where the inhabitants can respond to respectively love, hate, happiness and fear, determining the intensities of their feelings. Each evening the tower transmits the colours as “the State of the Town” assuming the most intensely emotions as a large interactive system of relationships.

Personal messages can be placed in a capsule underneath the tower as well as the tower will present a prize to the address in the city that scores the highest level of emotions.

Hotel Habitat, Barcelona

Hotel Habitat is a hotel by Enric Ruiz Geli, Max Zinnecker with James Clar with its most significant characteristic as a 3.000 m2 stainless steel mesh as a tensegrity structure offsetted from the concrete structure and glass facade.
The design concept is presented as ´your room in a tree´, where each leaf on the steel mesh consists of one photovoltaic cell, a battery, CPU and a RGB LED which creates an artificial light cloud around the hotel.

How it performs:
The ‘energy mesh’ has individual nodes with photosensors that collect the sun’s energy during the day and at night gives off a specific color according to the amount of energy collected reflected in an ´energy diagram´. The mesh consists of 500 tri-color LEDs controlled by a PIC microprocessor making the skin a thermometer as a ´performance architecture´; an architecture of particles.
There is no central computer controlling the light, but the appearence is reflected in the overall expression of the performance of each individual particle.

Tunnel of Light – Nydalen, Metro Station, Oslo

The Metro Station, Nydalen, in Oslo, contains an interactive installation located in the tunnel at the 30 sec. ride with the escalators connecting the ground level and trains. The metro station is designed by architect Kristin Jarmund, and the Intravision System developed the interactive installations.

How it performs:

The sound and light system consisting of 1600 CCL light tubes and 44 loudspeakers variate the light and sound patterns depending on the flow of people to and from the trains creating a 30 sec break from the daily routine.

NoRA – Nordic Research Application

The NoRA structure designed by students of Architecture & Design, Aalborg University, was presented at the Venice Architecture Biennale as an interactive architecture exploring how advanced architectural computing and sensor technology could attach the individual perception of place to temporary structures acting as agents for urban experiences. Architectural entities often closing up communication with the urban environment were questioned in a media architecture where the ‘capsules’ of urbanism contains a particular quality.

NoRA - night 1 

How it performs:

The structure is able to be disassembled and moved to other locations as research platform, exhibitions and show kitchen. The satelites located around the building are tracking the flow activity using infrared cameras and translate this signal into a variating light and sound scheme. During performances the building sound, light and cameras can be controlled by the performers and the activities recorded to database and the internet.

Performative Startup

The blog for the research project, Performative Environments, by Bo Stjerne Thomsen, is now starting up.

This blog will contain example projects and links to performative related designs.

Enjoy !
