Bird flight simulator. The boy goes for altitude and distance, the girl does stunts.

In the bird-flight simulator at the Pittsburgh Aviary, the girl twists and turns, careening around buildings, dive-bombing alleyways, and comes to a perfect landing in the middle of the street just as her timer runs out. The boy immediately heads up to clear the buildings, then flies toward the horizon to see how far he can go.
