The first example in media is not too different in implementation as the other real world examples. This is the logo for a popular online first person shooter called Team Fortress 2. The illusory contour present in this logo is the circle formed by the empty space between the 4 slices. However, because of the surrounding black background, we perceive the black shapes as obstructing an orange circle. This gives the logo the effect of appearing more like a set of crosshairs, befitting for a first person shooter.
