I figured people would want a version they could read. The one I put in the comments had crap resolution.

I actually understood that. Let me explain in the most basic terms I can use.

The beginning part has no major significance. What I'm going to explain is how the letters are recognized

There's a thing called ASCII Short for American Standard Code for Information Interchange and what it basically does is translate a number between 0-255 into a letter.

In binary, each unit (moving leftwards) has a value that's double of the previous number. Much like our number system where 10 is ten times bigger than 1. In binary, 10 would be only two times bigger than 1. Given 8 binary digits (or bit for short), the computer can create a 2 to the power of 8 (which is 256) different numbers which then correlate into 256 different characters.

The QR scanner reads this in a specific order, which is shown in the gif and thus translates every batch of 8 bits (or more commonly referred to as a byte) into a character. COMPUTER SCIENCE!

Could somebody make a QR virus that when scanned will **** down apple devices and everytime it boots up it shuts down after 30 seconds? Id love one, so I could print and post in school.

It doesn't work that way. Unless you have an app that will execute (extremely) small programs written into the QR code, the best that you can do is send someone to a website that does what you want it to do. That being said, there hasn't been a web crack for ios in a number of years.

"Can anyone draw a doodle that, when looked at, makes people go blind, and causes internal bleeding? Viruses can do that, so this should be possible. I want to hang it around my school. People need to learn that their immune system isn't a safety net."

You tried to make fun of two separate comments at the same time so that didn't really make any sense. I'll just say this in response though. If the last 50 years have taught us anything, it's that impossibility only exists in our minds, as we can only do as much as we can imagine... if that makes sense.
