We're interested in the development of a "Now and then" plugin that would allow selected images to be overlaid with a newer image of that artefact/historical landmark etc. and then "peeled back" to reveal the original image underneath using a mouseover effect.
The effect I'm looking for is something like this: http://www.abc.net.au/news/specials/japan-quake-2011/
I guess there are several ways of creating criteria for linking two images together that could be used to support this plugin, eg.
-Could be an extension of the exhibit plugin?
-use of the dublin core "relation" element?
-a specific "now and then" item type?
Does this sound like a worthwhile project? Anyone interested in quoting for this?
