Nexus+ is another project I'm working on to see how a white version could look like with a larger (wider) screen.
Weather Widget is one of many other widgets I'm working on that has the same layout as the Google Glasses.
Music player is visible at anytime you wish by simply swiping up from the black parts of the soft key menu.
Notification bar is the same style that is found in Jelly Bean with Google Now notification style which shows a faded image of the application the notification belongs to.
This is still a work in progress and I will have more mock-ups uploaded when time allows.
Everything was done with Photoshop by me except the handset template (originally black) that I cannot find the owner for. So kudos to him/her for an excellent design.
Another screenshot has been posted to show how the Play Store notification is expanded instead of the G+ one.[link]
Thanks and always appreciate comments.
