Robot gets the cookie. But I cant fucking believe it. I think it has something to do with a certain online community... For anyone who's still looking:
Google better explain themselves. I love how only the nerdiest and most retarded people of the internet have found it. I got banned from fark today, i'm so proud
Even with Weltall's clue, I couldn't find it until I looked at lazy's zoomed in images. Whoever discovered that has way too much time on their hands, or it was just a strange coincidence that their eyes landed on that exact spot on the picture and they noticed a Triforce. And I'm the type of person who notices Triforces everywhere all the time. For example, there's this one ad that has several triangles together and is an IQ test of some sort asking how many triangles are in the picture total. I pay more attention to how many Triforces are in the picture though. :)
Amazing how such a simple image of three triangles could become so iconic.
