Here is my final Analytics Engine.
The sandbox mod files are here.
Here are some parts of the flowgraph:
The part which forces the blocks:
The part which controls the xml and time-of-day:
My idea is to use the lighting data from the pachube feed, and represent it in a similar way as the student who created the feed, but on a grander scale. She used a series of blocks covering a window, I plan to use a series of blocks covering the entrance, or inner section, of a cave. Instead of having the blocks rotate to let more light in, my idea is to have the blocks literally explode out of their locations onto the ground, possibly accompanied by a sound effect, as the amount of light outside increases, as though the light itself was a force. As the light decreases, I'll attempt to make the blocks float back into place, but may end up just teleporting them back.
I'll also include a light meter inside the cave, behind the block-wall, to allow the viewer to see what's happening in a more quantitative fashion, which, when combined, should give an easily accessible interpretation of the data feed to the casual observer.
I decided to use the observational mode, though with a few captions to assist the viewer with conceptual ideas which may not be immediately observable. This allows the viewer to create their own idealistic links between the concept of Pure War and the installation. This mode also gives the carefully chosen soundtrack a more prominent role, giving the viewer another aspect of Pure War, the constant but smooth and steady flow between various states of power and influence.
This documentary mode tends to restrict the amount of technical information which can be conveyed to the viewer, but that technical information doesn't need to be presented in this particular case, as the accompanying model and level files allow the viewer to access that data directly.
