Perhaps the primary issue that I am researching is that of the medium in which the image is to be displayed. For reasonable resolution, this needs to be something in which waves can travel very efficiently. Visualization of electromagnetic waves would be ideal, transverse displacement waves (i.e. the medium could be... water) would be sufficient to display the concept.
Another interesting idea draws from Chladni plates, which show the harmonic behavior of plates through the spreading of sand. In other words, when struck with a rosined bow, standing waves occur in these plates, upon which sand or other material settles in the relatively stationary regions of the specific (predictable) harmonic maps. So, other possibilities include floating oil on water, with an apparatus that allows the setup to be placed on an overhead projector, and/or sand/particles on a planar membrane.

Through discussion, the issue of addressability fell onto the idea of fourier composition of images. Most interesting is the notion of three dimensional fourier transformation of a three dimensional image, which would lend itself to three dimensional electromagnetic addressing in a compound that has significant depth, width, and height. Eureka.
In the mean time, staying within the scope of the class, I've decided to set a semester goal of producing a two dimensional display that is addressed through edge wave modulation. The idea is that a given image will have a discrete edge wave fourier transform (surrounding the entire image), and vice versa, such that reproduction of the edge wave condition should reproduce the contained image. I still need to check on whether this premise is true... there may be some subtleties that I have not yet recognized.
This would be an interesting means of testing this method of addressing with 2/4 edges (i.e. assuming that you may arrive at multiple images, given, for instance, 2/4 edge wave modulation, how might one control the resulting image?), and the physical edge pattern or continuity required to develop a display with reasonable controls and resolution. Ultimately, this would inform the potential application of these methods in three dimensions, such that a portion of the contained space is exposed for viewing.

I'm still debating whether to chase down the specifics of electrochromic or electronic ink materials (?). What I'm looking for is something that is basically a combination of the two, with the opacity shifting abilities of electrochromic materials, and the addressability of electronic ink. Both operate as non-emissive devices, which is good. I am thinking that electrochromic technology would be the basis for the project, but three dimensional localized actuation does present a significant problem (the good kind of problem).
