[ WP ] Two Earths from two parallel universes managed to establish contact . They work together on the biggest `` Spot the difference '' game ever .

It had been two months since WALDO had begun processing and comparing the combined digital history of the parallel universes. Cheekily named after the character from the popular book series, WALDO was the product of months of planning by top AI engineers and data processing technicians. Using Google and local information from databanks all over the globe, WALDO would take the top 100 recurring keywords for a search in order to create a hexidecimal code to represent the profile for all events in history, famous people, biological processes, George Clooney's internet history, foods on a stick, 1 star restaurants on Yelp, lists of medical burn centers in the United States, superhero prompts on a subreddit, and trillions of pieces of information that comprised the recorded digital collection of humanity's understanding of the known universe. 
 
 Many bottles of champagne were popped over the creation of the project and now, both parallel universes had nothing to do but wait as WALDO silently carried out its sole purpose. 
 
 `` Dunnigan, where's WALDO at?'' 
 
 Originally meant as a joke from his supervisor, the question became a source of frustration for both as days turned to weeks and weeks turned to months. Media interest had already moved on to a famous celebrity divorce, as WALDO continued its process diligently with no end in sight. 
 
 `` Well, sir, same as yesterday. No change in activity levels.'' 
 
 `` Alright, well let me know if anything happens, I guess.'' 
 
 `` Sure thing.'' 
 
 Craig Dunnigan minimized the processing usage tools that tracked WALDO's level of activity and resumed playing Fallout 4. 
 
 `` Another Fat Man? Come on...'' *Beep* 
 
 `` Hm?'' 
 
 Craig alt-tabbed out of the game to see that the activity readout, which had until now remained relatively constant, had taken a sharp decline in the last ten minutes. 
 
 `` Walt... WALT! Get in here!'' 
 
 He heard the sound of chair wheels sliding, a door opening, and then running footsteps. 
 
 `` What happened?'' 
 
 `` It... appears WALDO's finished.'' 
 
 `` Alright, well where's the anomaly? Pull up the data.'' 
 
 After a couple of clicks, Craig had pulled up the Master Sync List. 
 
 `` What am I looking at?'' 
 
 `` Well, these columns are every bit of information that was processed, but in order to save space, the information that matches up exactly is compressed and categorized. So any anomalies are going to take up more space since WALDO intentionally has no process for dealing with search terms that do n't have exact keyword matches. So I just have to sort by size... let's give it a minute. And there it is. This code. This is the difference.'' 
 
 `` Well, what is it?'' 
 
 `` It's in the beta column which means it's something in their world that we do n't have. WALDO is loading up relevant local files as we speak... Damn, this is exciting! Ok so it appears that the relevant files were n't a search term but local files. And... they come from the United States Federal Government! Well theirs, not ours. File source seems to be... well... the Department of Defense... No, it ca n't be. They're plans to... Oh, God, help us.''
