The image was created for E\&S by motion-graphics designer Ryan Luse. But that?s not all it is. In keeping with the issue?s theme{--}noise, and finding the signal within the noise {--} we?ve hidden a signal on the cover as well. It is, appropriately enough, the word noise. Can you find it? Here?s a hint: Check out the light-colored ?spikes.? Still can?t see it? You?re not alone. We?ve created a highlighted version for you on E\&S+.
