Mysterious crop circles appeared in Salinas, California on December 2013 and as usual, it caused people to speculate how they got there and whether they were left by humans or extraterrestrials. Although there were some crazy theories put together by alien enthusiasts, Nvidia announced at the Consumer Electronics Show that it was all a stunt to promote its new 192-core Tegra K1 processing chip.
The crop circle itself does look very much like a computer chip and one of the clues that ties it to Nvidia is the number 192, which was spelled out in braille at its center.
The hoax even went as far as having two guys driving in California shoot a low-quality video "discovering" the crop circle by following an unusual green light. The whole stunt had viral appeal and it was quite a clever way to promote a technology that’s so advanced, it almost seems like it could be alien-made.
