Many years ago, when your trusty blog writer and photographer were little, we used to open up each new issue of National Geographic’s kids magazine and look for a feature called “What in the World?” It was a quiz game where they would show an extreme closeup of something rather ordinary—a pencil tip, or a junebug, or a flower petal—and the reader had to guess what it was.

We thought we’d play a game of “What in the World?” on the Project CONVERGE blog. Let’s see how good your memories are: Each of the first six photos in the slideshow is a closeup of one of the photos that has already appeared on the blog. As you look at each one, try to remember where you’ve seen it before, and guess which post it was in. Then keep clicking—we’ll show you the full photos in the second half of the slideshow.

Are you ready? Click through and see how many photos you can identify:
