Although the Chinese couldn't tell anyone exactly what an earthquake measured on the Richter scale (since the Richter scale wasn't created until 1935), they did manage to invent the world's first earthquake detector -- a seismograph. Not only did imperial astronomer Chang Heng create a seismograph during the Han Dynasty in the early second century, he created a magnificently beautiful one.
Perhaps you already knew about the pyramid complex on the Japan seabed, but even more interesting is the discovery of the pyramids in Bosnia. Someone named Semir Osmanagić claims has discovered pyramid complex in the Bosnian town of Visoko. One tunnels network said to be the tunnels that connect with other pyramids. Many scientists claimed this discovery was a joke but some of them are participate in a conference of scientists in an attempt to investigate the pyramid further more. If you look at the video judge by yourself whether it's natural or artificial. This Paper model is inspired from the three major pyramids, Pyramid of the sun, the moon and the dragon.
I found this idea when I was reading one of my daughter kid's encyclopedia about ancient egypt. I thought it would be a beautiful model if it could be turned to paper model. One night to complete this model as I expected before. Here it is, 3 pages patterns for a nice miniature of ancient egyptian game, Senet. They said it already played since 5000 years ago or around 3000 before the born of Christ.
