CNET posted articles after conference presentations on Adobe's 3D camera lens (October 2007) and a Stanford University project using a multi-aperture image sensor (February 2008).
There's video of both projects: at Stanford (YouTube) and at a French website featuring a nice Adobe presentation (a shorter audience sample is on Flowseeker). John Nack posted additional details in October. I'm not sure how the projects are related to each other, or to Refocus Imaging in Mountain View. All 3 use some of same images.
By the way, Bill Moyers hosted an interesting video on photography and consumption by photographic artist Chris Jordan.
