Update: Pipehenge and the desktop Earth-Space Simulator may no longer be available. An Internet search shows that the two web sites for Pipehenge and the ‘ESS’ are no longer available, aka no longer in use. The best references for the Pipehenge are on a web page written by one of the developers, John Dunlop of New Zealand. Also, click here to go to the Pipehenge YouTube web page to see a collection of short video clips featuring Eric Jackson explaining and demonstrating the Pipehenge model.



Watch a short demonstration of the Portable Pipehenge by Steve Bevan.
Bring the Pipehenge indoors with a desktop model called the Earth Space Simulator. This arrives in kit form and takes a short while to assemble into a hands-on model that simulates the apparent motions of the sky for any time of the year and for any latitude. It is an ideal teaching tool, for example, the effect latitude has on the Sun’s daily and seasonal apparent motion from sunrise to sunset.
