An intricate crop circle that appeared in the small town of Chualar wasn’t created by aliens after all. NBC-Bay Area reports Silicon Valley chip-maker Nvidia is behind the circle — first spotted one week ago by a photographer flying over the area. It turns out the company plowed through the grass to gain publicity for its new mobile chip, which has 192 cores. Braille experts confirmed last week that the numbers one-nine and two were found inside the circle. Nvidia’s website has already been taken over by a picture of the elaborate design.
