Maybe something similar has been done, but I haven't seen it - it's called "FrameMe". It is a nice, quick, way to get to multiple photos - if you have kids and use your phone to show people pictures, it's pretty handy. It basically makes 1x1 widgets (with different frame styles) of photos you can place on your home screen. When you click one, it quickly pops up into a fullscreen (essentially) view. If there are other FrameMe widgets on the homescreen, you can simply swipe back and forth to view those instead of closing the first and clicking on another.
It's essentially like making a mini photo gallery of your favorite photos on your homescreen, but it's much quicker than accessing the main Android gallery, and the pictures view bigger and better than the stock Picture Frame widget.

xda-developers - View Single Post - FrameMe - The easy way to show off your favorite photos [Update 9-10-10]
It's available free through the XDA link, but it's only $1, and we should all support our devs for the work they do for us.
