The Sidereal Wall Clock

A square screen with the live dial at its heart. The Hand of the Cross carries the Southern Cross around the pole, beside familiar hours, the months, the Sun, the Moon and the planets.

The four corners are working readouts, never decoration.

The solar system on a large touch screen, for a wall or a table. Turn it with a finger, pinch to come close to a planet, and roll time forward or back to see where every world will be.

Leave it alone and it drifts back to tonight's sky, ready for the next pair of hands.
