We recently covered Twitter's roll out of what it calls "expanded tweets," and now you can add Lytro's interactive images to the list of supported embedded content. This means that images taken with the light field camera can have their focal point, or depth of field, adjusted right from your Twitter stream rather than following a link out to Lytro's photo sharing site. Be patient, though, because this feature "begins rolling out today," so it might take a bit of time for it to take effect for everyone.
