This is an example of one of the many draft interfaces and layouts that were accomplished in the early development of NASA's award-winning "Earth Observatory" website. I was co-responsible for the design, conceptualization, and interactive presentations of this website concept to seek support and funding (both internally and externally to NASA). This example was still in progress as a draft at this stage.
Although the final design was altered considerably (to favor more text and static graphics in online publication than the original anticipated multimedia), the structural concepts of an "Observatory," a "Study," a "Library," and so on, were largely my idea: I sought to deliberately use well-known metaphors to facilitate user-friendliness and flexibility in real-world use.
The above design shows how I like to "zone" out the interface in advance and get a sense for it's psycho-kinetic balance (hence, you can see a lot of "place-holders" where there could be input or output depending upon mode). This particular layout was done using Canvas. I hope to write more about this award-winning project, my design reasoning, and my contributions to this website at a later time.
