I was sent a pretty interesting link to a photo app that does have some potential. TiltView shows a bunch of photos in a grid, the twist is that the images can twist. When you click on an image it fills the screen. That in itself isn’t that special, but I think if you took that grid and multiplied it a couple times it could add some value to finding the image that you’re looking for. You can read more about TiltViewer on their blog at Airtight News.
