This orrery is really quite wonderful! Not only is it a great demonstration of what CSS can do, it’s a really accurate visualisation of the solar system.

The Long Now Foundation has been posting some great stuff on their blog lately. The latest is a look at orreries, clocks, and computers throughout history …and into the future.
