Hard to believe this hasn't been posted before.
Vertical jets of air from perforations in the surface of a table suspend planetary spheres and their moons above it in a moving display of the solar system.

The earth could have a small weight mounted on a
track inside along the antarctic circle. This would
cause it to always hover with the correct tilt on
it's axis. There could be some small fins or
subtlety distorted shape to cause rotation
aerodynamically. |
|
|
I'm not sure if there would be a way to keep the
direction of the tilt constant to show the seasons
properly, and of course spinning it aerodynamically
would make it hard to get the right number of
days per year. |

By tinkering with temperature and humidity you might be able to simulate atmosphere (+) |

[scad], easier to project the image of the planet from a tiny lens
concealed in the Sun's equator. That way it can just be a neutral
sphere. Even handles eclipses correctly. |
|
|
The Saturnian rings would be tricky, though. |
|
|
This is an awesome idea, truly. |

[+], and I am horror-struck at having but one bun to
offer. |

Nice idea - initially I thought it was a terrible idea, but that's because I misread the title as "Canada Orrery" |
|
|
What, like an orrery that goes round in ever decreasing circles ? |
|
|
I love the projection idea. Would be great if it was
big enough to walk around |
