   This is worth sharing.

   It's an animated GIF where every frame is a valid QR code that leads to the "Never Gonna Give You Up" rickroll.

   That's kind of amazing.

     Worth noting for anyone who can't see it that the novelty is that these valid QR code frames together also form a grainy black and white animation of Rick Astley dancing!
     
     I wonder, are they all interpreted as the same QR code, just with different noise added, or are they actually pixel by pixel all correct QR codes that are somehow reformulated to form a different Rick Astely shape?

     An explanation I saw in the original birdsite thread but haven't verified myself:

     > It took me a moment to work out what they had done. This is actually a low density QR, with each pixel of the QR done as a 3x3. The centre of each 3x3 is fixed, and is what will be read by the QR code reader. The other pixels are used to make the animation. Clever.

     @atoponce This is one of those rickrolls that tell people in advance about it.
