It's fun to take a look back at the Seattle that was, but how about taking old Seattle and new Seattle and seeing what they look like side by side? That's the idea behind Timera, an app that allows you to create combined images of past and present in "rephotography style." The end result is an image of a building or street that combines how it used to look with how it looks now. It's something a few people have had some fun with around Seattle. Check out some of the images that have been uploaded and get to making your own right here.
