World Wall Maps
"One World" beautiful poster showing 3-global views of Earth Time Zones of the World The Geochron World Time Indicator - analog electronic clock-map... The Geochron demonstrates precisely where the sun is rising and setting every minute of the day. It's face is a Mercator map of the world, illuminated to simulate the suns light as it is cast on the planet. The map scrolls left to right at a speed of 1" per hour - complete in 24 hours. The light pattern changes slightly day to day to progress through the seasons. The time of day (or night) is indicated on the time scale. Calibrations are at 5 minute intervals and more precise calculations can be made on an optional minute dial. Back to A-Maps and Graphics |
