In talking with Niloy Mitra, I noticed he had a cool QR code on his page. I asked him about it, he pointed me to this decade-old work he coauthored. Searching a bit more, I found a cute web browser version for making your own. It’s a bit flaky, in that a lot of the images I tossed in look really bad half-toned. Maybe if I had a clue what the options were it’d come out better. But, with one it worked pretty well! I just put in the URL I want the code to lead to.

Addendum: but wait, there’s more! Another generator, from the author, that also permits color output. See my next post.
