Ooh I likey. Can we change and morph the shape and size of the Earth at whim too? |

Variocentric Orrery $129.95 Flat Earth/turtles-all-the-way-down expansion pack $59.95 Causing Ptolemy to continually spin in his grave... priceless. |

Excellent! This reminds me of another idea, which I've been meaning to post for a while... |
|
|
You could have a rotating, telescopic support arm for the sun, obviating the need for changing the support. |
|
|
Problem is, the planetary arms would give the game away, demonstrating it to be merely an offset heliocentric model. Better to have each body mounted on a seperate, rotating, telescoping arm. |
|
|
If each body was formed as a coloured / printed rubber ballon, their relative sizes could be adjusted by a base-mounted air pump. Possibly some kind of scale/laminar-construction could be used for similar effect. |
|
|
It certainly would be nice to give no indication of the mechanism, and let the viewer decide on what makes the most sense to have at the centre. |
|
|
One day I shall build a variocentric orrery out of brass (possibly with the option of interchangeable flat earth/great a'tuin) but in the mean time I have built one out of javascript. |

Thanks for a fun half hour [mitx]! |
