Search for the Blindeye

Searchfortheblindeye.com is a Gravity Falls related website that launched on August 1, 2013. The name is based off the cryptogram deciphered in the end credits sequence of "Gideon Rises." The site is not affiliated with Disney, as stated by Alex Hirsch on his AMA. It is currently unknown who runs the site.

The site
The main page of the website has an animated GIF of Bill Cipher, with a version of the theme song from the credits of "Dreamscaperers," playing on loop in the background. Below the animation is a Combined cipher, which is seen in every image of the following dates, it reads "9-21-4-9-22-19-6-18-15-6-5-4." By clicking on the cipher, it decodes to "OCTOBER FIRST."

The source code of the page contains an ASCII art image of Bill Cipher. In the letters and numbers comprising the image are messages that have changed every day since its discovery. Words hidden in the image appear to be written by one individual, while cryptograms are written as if snuck in by another. The original writer seems to not want the cryptographer to get his messages out.
