I found this on www.dpreview.com it’s making the Lytro camera more and more interesting :
Lytro has released a firmware update that enables the Wi-Fi chips inside its 8GB and 16GB light field cameras. The San Fransisco-based company has also announced a new iOS companion app called Lytro Mobile, which allows you to browse images from the camera on an iOS smartphone or iPod Touch. Replicating some of the functionality of Lytro’s existing desktop app, the mobile app allows you to refocus and change the perspective of your images and share the ‘living pictures’ via social media.
