Further to yesterday's post on the nature of imagined data-spaces, this article by Peter Anders provides a nice introduction to qualifying different kinds of virtual spatial-transformations (if you're into that sort of thing). From the article:
Implicit in any cyberspace community is a space, an environment that embraces the domain’s activity. Engagement with such communities depends on it. This space is founded on our physical experience...In this paper I will describe the relationship between cognitive and perceived motion and the shape of various communities formed in text and graphic environments. I will present categoric and dynamic motion as concepts for understanding movement in these spaces and as an issue that affects their design and use.
Personally, I found it a very interesting read. Anders explores similar concepts here and here. Meanwhile, on an altogether unrelated note, our baby has dropped.
