Mechanical marvel: 10,000-year clock fixes time in relation to our astronomical neighbors

And if you step on this thing, it gives you your weight and horoscope.

From Environmental Graffiti:

The world is changing so quickly that trying to imagine what life will be like in five years’ time is difficult, let alone ten or even twenty years. A hundred years requires a pretty impressive leap of the imagination, and a thousand, well – even scientists have trouble trying to guess what people will be up to then. We really don’t know what life on Earth will be like far into the future, or even if there will be life still present. But if there is, and if it is sentient, perhaps some of these life forms – human or otherwise – will wonder about the people who lived up to 10,000 years ago, and why they left a giant clock ticking away inside a mountain.
