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.

Promise, when Haiku kernel will be rock solid, we'll remove the qrcode feature and use instead a disk log writer. Happy?

Please don't remove it (looks like you're involved?), I think it's great / brilliant / cute, an awesome idea... maybe even all informational popups etc. should have qrcode?

Though, I can see one downside - unpleasant shudder when seeing some random large QR code somewhere. ;)
(kinda like my buddy used Windows error sound for SMS arrival, which made some people in public transport visibly disturbed, a bit)

Now I also wonder if QR code (~animation?...) could be extended to quickly transfer smallish amounts of data; I imagine it could possibly often be more immediately intuitive than bluetooth or wifi.
