I am no photography buff, but this seems pretty incredible. I really enjoyed playing with the images in the gallery, especially the ones that involved glass/reflections.
With such a small sensor camera I doubt the depth of field is such a problem that this technology would be useful. Put it on a full frame camera body and you have my attention.
