Hey there, first of all we noticed the error in the disclaimers (which we didn't see before they published the project) and by now they have corrected it
The little thing you have noticed are the Easter egg they put in the Infographic (this one was a surprise too!), but we can't talk abut them till they officially say what they are, but you already did an awesome job discovering them, can't you tell who they are based on the little objects, I'm sure you can!
I can say, though, that it was an incredible experience to be part of the team, one I'll never forget, so if you have any questions you are welcome to "use me"
