I’m reading my copy of Wired magazine, and I happen to glance at an ad. It’s a photo of a bunch of athletic-looking legs, and one artificial limb. I’d guess that the athletes are supposed to be at some kind of ceremony, because there appear to be petals on the ground. However, beside one athlete’s foot, there’s two small objects. One might be a power bar wrapper, but it seems to have an odd shape. You can view the ad with the object magnified. What is that thing, and why is it in the ad?
