The Globe: where
Drag the planet and let go. It keeps spinning, slows down, and the nearest city swings in under the crosshair.
The throw: both at once
One tap picks a place and an era. The globe and the dial move together and settle on the next find.
The dial: when
Ten decades, 1930 to now, on a drum that clicks into place. The year lights up as it comes under the glass.
