We don’t know exactly who it was who made this tree, but it truly is a work of geeky Christmas genius.
Added: Since this article’s initial publication, I’ve heard from Jason Roberts and Ryan Kelly, two of the people responsible for making the tree. I’ve added a photo sent by one of them that “proves” that the portal works, after the jump. Congratulations, guys, for coming up with a simple but awesome geeky Christmas idea.
