Towards the beginning of the movie (Wreck-It Ralph), Ralph puts on some sophisticated armor, and the audience gets a glimpse of the inside of his helmet, as if seeing the world through Ralph's eyes. The helmet shield is a jumble of information:
That's a bad picture, but watch it on the Blu-Ray and it's pretty clear.
There are plenty of dials and gauges in this view, and that's to be expected. You'll notice, too, that on the bottom right corner is part of a hidden Mickey (just his ears are poking up). This is a not-very-hidden hidden Mickey, as the Wreck-It Ralph website and Blu-Ray disc both divulged this information.
In the upper-right corner is a tic-tac-toe game that continues to be played throughout the shot.
On the right-hand side is a list of different systems and their statuses:
Each of these systems has the status of "Checking," which then changes to "Online". The GasSys goes Online almost immediately, then the others follow. ArmPlt could stand for Armor Plating, but it also looks like ArmPit, which is funnier than Armor Plating.
On the left-hand side of the screen is some scrolling text. These are apparently instant messages from members of the Hero's Duty game, namely Calhoun and Marco. Here's what I was able to make out:
Calhoun: Report in, Squad! Any of you ladybugs seen Markowski?
Marco: Golly, I haven't seen him since 03:00 hours, Sarge.
Calhoun: What is he doing? Practicing the ballet?
Marco: He was freaking out, Sarge. Kept going on about the bugs...
Marco: I don't know if he's Corps material, Ma'am.
Calhoun: Corps material or not, if he doesn't get his bright, shiny boots back to start pose by quarter drop, I'll have him transferred to Undead Apocalypse slathered in meat tenderizer.
The visor also lists 190,499 unread messages, though other sites are listing it as 790,499, so maybe I misread that.
I've only found one other hidden Mickey so far (aside from the ones they pointed out on the Blu-Ray), but I will save that for another day.
