The quality of choices in manipulating the tools towards intentionality and meaning is the technology. A pencil is a link in a chain of rings that provided a technology of externalizing thoughts, emotions, spirituality's and other senses into a tangible reference. Technology is the system that gives our voice an audience. Idea becomes substance because of technology. In all senses of the definition we homo sapiens have been exploring technology for hundreds of thousands of years.
Technologies give rise to many ways to communicate.
The choice of which technology to use, gives our ideas articulation, nuance and variation. Art and technology implies there is a connection between the choice of tool and process as it relates to intent. As communicators we must find many ways to express ourselves, so as we move through life experiences we articulate our ideas for each new encounter. What computer technology does, is give us a broad range of choices in output. Variation on variation is at your finger tip.
