Colony collapse disorder (CCD) or sometimes honey bee depopulation syndrome (HBDS) is a phenomenon in which worker bees from a beehive or European honey bee colony abruptly disappear. While such disappearances have occurred throughout the history of apiculture, the term colony collapse disorder was first applied to a drastic rise in the number of disappearances of Western honey bee colonies in North America in late 2006. Colony collapse is economically significant because many agricultural crops worldwide are pollinated by bees. European beekeepers observed similar phenomena in Belgium, France, the Netherlands, Greece, Italy, Portugal, and Spain, and initial reports have also come in from Switzerland and Germany, albeit to a lesser degree while the Northern Ireland Assembly receives reports of a decline greater than 50%. Possible cases of CCD have also been reported in Taiwan since April 2007.
The cause or causes of the syndrome are not yet fully understood, although many authorities attribute the problem to biotic factors such as Varroa mites and insect diseases (i.e., pathogens including Nosema apis and Israel acute paralysis virus). Other proposed causes include environmental change-related stresses, malnutrition and pesticides (e.g. neonicotinoids such as imidacloprid), and migratory beekeeping. More speculative possibilities have included both cell phone radiation and genetically modified (GM) crops with pest control characteristics, though experts say no evidence exists for either assertion. It has also been suggested that it may be due to a combination of many factors and that no single factor is the cause.

Pad.ma is a web-based video archive, launched as a public website http://pad.ma in February 2009, that works primarily with footage and not finished films. Pad.ma’s interface offers some exciting new ways in which moving images, timelines, text and maps can be linked. It offers a practical technical and legal framework through which footage can be shared. It makes an appeal for thinking about film and video “production” in a number of different ways: as a filmmaker publishing video that is not a film, as a film editor organising footage using the archive, as a writer across one or many video clips, as a scholarly researcher or film student contributing notes or using links to clips as references, as a filmmaker reusing another’s material, as a programmer building further applications using pad.ma’s open source software base, for example.

Pad.ma a collaborative project initiated by five organizations: oil21.org from Berlin, the Alternative Law Forum from Bangalore, and three organisations from Mumbai: Majlis, Point of View and Chitrakarkhana/CAMP. The entire archive is searchable and viewable online, and is free to download for non-commercial purposes. This offline exhibition reveals the many potential ways in which pad.ma can be used.

The idea is to detect bio feedback of plants from the okno open_green, send these data from the garden (over a radio frequency connection) into okno_inside, transform them into generative music and stream them over the okno_radio.
After a collective brainstorm, different parts of the project are setup and worked out by different people. At the end everything fits into one project.
We discussed possibilities to measure subtle activities of plants and create a human/plant interaction. We discovered that all plants in the open_green are showing a highly complex biodynamic response to their environment.
We conducted experiments to try and find out how plants react to wind, air pressure, touch, light, movement, sound etc.

1. sensors:
We were experimenting with different sensors on stems, flowers and leaves observing data and biodynamic responses. First we looked into measuring the bio resistance of the plants. We tried to build a galvanometer based on the Backster experiments.
Simultaneously we were working with stretch sensors: long thin pieces of stretch fabric were attached to the sunflower stems. When the flowers move in the wind, the fabric becomes more or less resistive and generates different data.
We worked with all kinds of conductive and natural materials used for measuring variable resistance: stretch fabric / conductive thread / graphite / metal wool / foil / wire / and the plants themselves.
We decided to work with 2 data types: the Slow Input where plants are growing and moving, changing absorbation of light and temperature (plant as actor); and the Fast Input: drumming, touching, knocking, talking, rubbing and pressing the plants (using plant as interface).

2. alternative powering:
We put small 4.5V solarpanels in serie to power arduino’s and sensors.

3. wireless connections:
The data are send via an internal radio network. We configured Xbee Radios with Xbee Shield via Serial connection (USB). Each Xbee is given an address/name/destination via AT commands. The arduinos are programmed to handle the data.

4. sonification and streaming:
The numbers we are getting in from the garden are becoming parameters and generators of our open_green sound. The data coming out of the 14 analog input streams are sonified via Supercollider create a nice ‘zen-sound’.
