S falls from Shack, goat eats it
The Gravity Falls Gossiper
Now with less typos (This is a grammatical error, as the word should be "fewer")
Lil Gideon in the Big House
"He could use a time out" - Bud Gleeful
What would a boring old man like Stan want with that book anyway? - Soos'd!
Soos' convenient appearance leads many to believe that he timed it perfectly, to keep the twins from figuring out Stan's secret. He definitely knows more than he seems to know...

passcode to lab
The passcode to Stan's lab is the alchemist symbols for composition, pulverize, digestion, and fusion. This code is also seen at the beginning of Journal #3 in Tourist Trapped.
gadgets and gizmos
The constantly working gadgets in Stan's lab seem to be futuristic. Many fans believe they were built by Stanley, before he disappeared.
looking glass
Apparently, there's a TV screen in Stan's lab, which, according to some theorists, comes out through the totem pole. Stan could be spying on Gravity Falls's residents.
Stan's tattoo on desk
The design of Stan's tattoo is seen lighting up the side of his desk.
picture of Dipper and Mabel
Stan keeps a picture on his desk of his great-nephew and niece. It shows that he genuinely does care for them.
papers on desk
These papers seem to be sketches of the superweapon Stan was about to create.
Finally, I have them all.
Stan says this at the end of the episode (though some people heard it as "we have them all", the international versions clearly show that Stan is saying "I have them all.") The obvious questions here are what he is going to do with the portal, and why he built it in the first place.
symbols on portal
The symbols are called Behenian fixed stars. They are 15 stars associated with medieval astrology.
Here we go.
What will Stan do with his new power? Will anyone else find out about Stan's power? Who is Stan working with? Find out next season...hopefully.
THE PORTAL WHEN COMPLETED WILL OPEN A GATEWAY TO INFINITE NEW WORLDS AND HERALD A NEW ERA IN MANKIND’S UNDERSTANDING OF THE UNIVERSE. PLUS, IT WILL PROBABLY GET GIRLS TO START TALKING TO ME FINALLY.
Well, we know what the portal does. This cryptogram on the page in Journal 3, though, is very vague. We have no idea why Stan opened the portal, or what he wants to do with it.
