Playing with the idea of "different perspectives on the same story"!

A QR code that sends you to a different source based on the angle.

@gvy_dvpont Got me thinking… can it be done without the lens? This one seems to work!

@isziaui Are you just half-toning the bits that are different? and the orientation of the sub-dots make them look more black/white based on direction? This is like 40X cooler than what I did

Toot

Written by Christian Walther on 2025-01-22 at 22:58

@gvy_dvpont Yeah, half of each pixel comes from one code and the other from the other. I assume readers sample in the center of where they expect the pixels to be based on the alignment blocks, so the important point is that the mask is the same on each pixel, and the center of the pixel lies on the boundary of the mask. So a slight shift of the picture tends to shift all of the samples to one or the other half.

@isziaui @gvy_dvpont That's mad. My phone seems to be happier finding the Masto URL, but I did get it to find the GitHub one too.

@isziaui @gvy_dvpont this is so clever. I love it. I bet you could do one that scans differently based on how far you are by having "high frequency" information that scans as one code that gets replaced by "low frequency" information as you get further back. I did something like this in college, but it didn't involve QR codes
