Lytro is a pretty neat gadget. The camera lets you take pictures and focus later. The technology is not perfect but has a lot of potential. Lytro cameras are not cheap anyway. FocusTwist is a cool application that brings a Lytro-like effect to your iPhone. It takes refocusable images you can interact with at a later time.
FocusTwist takes several images at different focus settings and combines them. The app is Twitter friendly. You will have to keep still if you want to capture quality interactive photos. FocusTwist is up for grabs for $2.
Speaking of cool products, the Nomad Keyring Lightning Cable is certainly one. It is a 3″ Apple certified Lightning USB cable you can attach to your key ring and carry with you. The cable is compact and allows you to sync and charge your iPhone. It is compatible with the latest generations of iPod Touch and iPad also.
These cables are not shipping yet. But you can pre-order yours for $24.99 at this time.
