An update on this crop circle that appeared in California on New Years Eve confirms that it was a publicity stunt by the Nvidia, a global technology company.
From Tech Crunch:
An intricate crop circle recently cut into a field two hours south of San Francisco baffled onlookers and spawned crackpot theories that aliens were responsible, but sources tell me it was created by Nvidia to publicize a big CES announcement. [Update: Nvidia confirms.] The design looks like Nvidia’s Tegra 4 chip, and though we can’t confirm this, it may be designed to drum up interest in the Tegra 5 chip Nvidia is expected to launch at CES.
Nvidia has a major CES press conference planned for tonight at 8pm PST in Las Vegas where it may fess up to creating the crop circle and is likely announce details of its new products.
[Update 6:30pm PST: Nvidia has confirmed it created the crop circle by adding this teaser image to its website.]
