May 16th 2013 - it was announced that a metal detecting Robot
while exploring previously unknown rooms beneath the Temple of the Feathered Serpent at Teotihuacan in Mexico.
Has uncovered hundreds of metallic yellow orbs between 4 and 12 centimeters across buried under the Temple.

The purpose of the orbs is unknown, but their exact locations are being mapped. Soon and it will soon be possible for

Could prove interesting.
