A few days ago I said the CA crop circle looked to me like a computer chip or motherboard. I suggested that it was part of some marketing campaign for a new chip or some other electronics toy.
That suspicion turned out to be dead on. From the article (and the confession):
It turns out the crop circle wasn’t the work of aliens, but instead – surprise! – it was a publicity stunt by Nvidia Corp., a maker of chips for PCs and smartphones.
