In the US, I believe that component in CRTs is called a "horizontal oscillator" instead of a "flyback transformer" (but could be that they are distinct yet related things). I've always been easily able to hear those, but am not usually bothered by them anymore since CRTs are fairly rare at this point. But this video proves that my 36 year old ears can still pick it up.

I feel like my hearing is bad -- I always want TVs louder than other people so I can make out what is being said, and in normal conversation it always seems like people are mumbling if there is any background noise at all. And I'm one of those annoying loud-talking Americans, especially if I'm talking on the phone (fortunately I don't get/answer many phone calls when I'm in public). But my hearing range pitch-wise seems to be exceptionally high, and not diminishing much with age (yet).

There's a fun easter egg for people like me at the end of that video. He put pulses of that CRT horizontal oscillator pitch where you can see the "Things You Might Know" text on the red background. I recognized it as Morse code, but couldn't decipher it even though I have an Amateur Radio license (I don't do code). In the comments at YT, people are claiming that the code translates to "never gonna give you up" -- so I guess he's Rickrolling people who both A) still have young enough ears to hear that 15kHz range *and* B) are old school enough to know / recognize Morse code. That's a pretty small target audience for an easter egg!

Nope, that's my own creation. I attended a Photoshop seminar last year (as part of an advanced vocational education course), but me and one of my classmates already knew how to use Photoshop, so we kept challenging each other to create strange and funny images throughout the seminar. You can admire our creations here: https://imgur.com/a/NFavi (but please don't share them, they probably violate a ton of copyrights ).
My profile pic is part of the first image. Our homework was to photoshop a small group of meerkats into a desert. I added a few more - and five pop culture easter eggs.

Walk near the minefield. Drop a bunny. Bunny walks bunny goes boom. Walk up to where the bunny went boom. Drop another bunny. Rinse and repeat.

You should be able to get across with an extra bunny or three. In the end game, you can use any extra bunnies on some moving machinery as a small easter egg. Ben likes it, anyway.

Rick and morty easter egg!

Nevermind. I replaced it with a YouTube video. You can still go to http://www.dorkly.com/video/78736/10-geeky-easter-eggs-you-can-find-in-real-life to try its brightcove embed code.

I had no idea easter eggs in video games could be so complex. It amazes me they figured this out. Anyone know of videos that show others that are this complex?

Also, there's SOOOOOOOOOOOO many little easter eggs in this that i've found, so i'll just list a few (that hopefully won't contain spoilers)

Lakeshire from Redridge Mountains is there
Dalaran is in the sky
Karazhan is there, with what appears to be an old Khadgar, or Medivh
there's a scene with a young Varian Wrynn
The scene with the alliance gathered around the table has a dwarf, and elves.
Potentially Sylvannas and Kael'thalas in it
Gul'dan is (Very VERY) briefly in this
The Dark Portal (not open, the wraith statue gate) can be seen twice


and there's a couple more very spoiler heavy ones i'll leave out.

And you missed all the easter eggs.

Haha, I did see this today.., Pretty funny.
If you didn't already know, here's the explanation for the cross-over.
