Earth, Moon and Sun Orrery Made of LEGOs

[HardOCP News]

Some guy built a miniature LEGO Orrery showing the Earth and moon orbiting the sun. According to the builder, the model is 97% accurate, with the moon orbiting the Earth every 28 days and the Earth orbiting the sun every 375 days.

97% accurate, unless you take scale into account and then it's hugely inaccurate.
