Ecolanguage.net uses visual animations to explain economical and ecological processes. The animations are planned for a common visual code to represent all issues involved with economy and ecology. They have just three types of transaction: yellow represent energy, red represents money and black represents information.
It comes pretty close to what I intended with the seminar called »Density«. In fact the assignments of that seminar started with visualizing the Grandfather Economic Reports by Michael Hodges. But in »Density« the focus was not so much on the visual code, but rather how visual representations allow rapid understanding. These two ideas are pretty close together. But »Density« is exploring the cognitive limits of understanding information in short time.
