Sigil ARG

Excellent read over at VICE on this article These Mysterious Symbols Have Been in 19 Video Games and No One Knows Why. It's a mouthful of a headline but the content is quite intriguing. There's a rather hefty Wiki article on the phenomena but, in a gist, an alluring image was found inside of the source code of a game and inside that image was a GIF that appeared to be part of a larger map. After continuous investigations, this same symbol and more map pieces - 19 in total (above) - have been found. No one knows where this ARG will lead but the discovery process seems like enough of a reward.
