I immediately thought it would be cool to use this as a temporary tattoo. Turns out there are companies that sell printer paper for this purpose, so it should be possible to print a QR code on that and transfer it to skin. Point your cellphone camera at the body art and presto! Website!
Then I thought of a scifaiku to go with the image. I made a QR for the Poetry Fishbowl Landing Page, but I just could not get the stupid thing to load with this post. Well, here is the poem anyhow:
Aim your camera here.
Wow, this used to be SF!
I love the future.
