In the effort to inquire the interactive relationships among different arts entities (various media and technologies, performing artists and technologists, performing and/or collaborating sites, etc.), here I start to sketch a few outlines along with some quotes from wikipedia. Please pardon these incomplete paragraphs.

• Media and Their Messages (Marshall McLuhan - understanding MEDIA)
  
  Throughout Understanding Media: The Extensions of Man, McLuhan uses historical quotes and anecdotes to probe the ways in which new forms of media change the perceptions of societies, with specific focus on the effects of each medium as opposed to the content that is transmitted by each medium. McLuhan identified two types of media: "hot" media and "cool" media. This terminology does not refer to the temperature or emotional intensity, nor some kind of classification, but to the degree of participation. Hot media are those that require low participation from users, since they foster detachment. Conversely, cool media are those that require strong user participation, since they urge users to engage themselves completely in their use. Radio, for example, is defined as a hot medium, since listening does not require complete involvement from the user. In contrast, television is a cool medium, since it requires more user participation. [from wikipedia]

• Media Ecology
  
  In 1977, Marshall McLuhan said that media ecology:
  
  ...means arranging various media to help each other so they won't cancel each other out, to buttress one medium with another. You might say, for example, that radio is a bigger help to literacy than television, but television might be a very wonderful aid to teaching languages. And so you can do some things on some media that you cannot do on others. And, therefore, if you watch the whole field, you can prevent this waste that comes by one canceling the other out.
  
  Inspired by McLuhan, Neil Postman founded the Program in Media Ecology at New York University in 1971. He described it as:
  
  Media ecology looks into the matter of how media of communication affect human perception, understanding, feeling, and value; and how our interaction with media facilitates or impedes our chances of survival. The word ecology implies the study of environments: their structure, content, and impact on people.

• Commensalism
  
  Commensalism derives from the English word commensal, meaning "sharing of food" in human social interaction, which in turn derives from the Latin com mensa, meaning "sharing a table". [from wikipedia]

• Mutualism, Commensalism, and Parasitism
  
  In ecology, Commensalism is a class of relationship between two organisms where one organism benefits but the other is unaffected. There are two other types of association: mutualism (where both organisms benefit) and parasitism (one organsim benefits and the other one is harmed). [from wikipedia]

• Commensalism and Symbiosis

• Resource and Service Relationships
  
  1. Resource-resource
  2. Resource-service
  3. Service-service

• Collaboration vs. Cooperation

• Collaboration vs. Sharing

• Dependence vs. Independence

• Additive and Subtractive Theories in the Arts
