Twin Clocks of Earth Mirrors North and South Sky
Twin Clocks of Earth shows the Southern Cross and Polaris sky as mirrored clock faces, turning Earth rotation into a teaching instrument.
The Twin Clocks of Earth is a paired astronomy instrument: one face reads the southern sky through Crux, the other mirrors the northern sky around Polaris and the Big Dipper. The point is not decoration. It shows that the apparent direction of sky rotation depends on which end of Earth you are facing.
Story
One rotation, two faces
The southern sky appears to wheel clockwise around the South Celestial Pole, while the northern sky appears to wheel anticlockwise around the North Celestial Pole. Twin Clocks of Earth places those views side by side so the difference becomes visible instead of abstract.

The month ring turns a clock into a calendar
The month stepper freezes the clock at local midnight and advances the sky hand around the year. That lets a learner see why a sky clock is not just a timepiece: the same rotating stars also create a calendar relationship through the year.
Story
Why this deserves a news page
Most astronomy explainers ask readers to imagine the geometry. Twin Clocks of Earth makes the geometry interactive: south and north, clock and calendar, Crux and Polaris, all on one page with the page doing the rotation in front of the user.
