BeOS & Derivatives Michael Lotz added code to generate QR-code for the KDL (Kernel Debug Land) ouput (which pops up when the kernel crashes). No more blurry photos with debug output, but a QR code which decodes to the clear-text KDL debug output. Here's one of the relevant commits, an example showing a QR code, and text from decoded sample QR code.

Not really... this is less of a WTF, and more of a "why hasn't someone thought of that before".

It's exactly the same old behaviour - dumping debug info to the screen on a crash - but it does so in a way that a reliable digital copy can be made (instead of a hand-written transcript, or a blurry photo of the screen). Brilliant.
