Classifieds thread

In addition to the emails from journalists, I also get a large number of emails seeking interactions with me—a discussion of cryptocurrencies, help in planning a political campaign, whatever—that could probably be had just as well, or better, with some other reader of this blog.  So inspired by Slate Star Codex, my lodestar of blog-greatness, I’ve decided to host Shtetl-Optimized‘s first ever classifieds thread.  This is your place to post any announcement, ad, offer, proposal, etc. that you think would be of particular interest to fellow Shtetl-Optimized readers.  As usual, I reserve the right to remove anything too spammy or otherwise unsuitable (“C@$H 4 G0LD!!!”), but will generally be pretty permissive.

Oh yes: Merry Christmas to those who celebrate it, from a spot roughly equal driving distance (about an hour 20 minutes) from Nazareth and Bethlehem!

Update: OK, let me start the ball rolling, or rather the photon propagating. Reader Piotr Migdal wrote to tell me about a quantum optics puzzle game that he created. I tried it and it’s excellent, and best of all clear: unlike virtually every other “quantum game” I’ve tried, it took me only a minute to figure this one out. (Admittedly, it’s less of a quantum game than an “optics game,” in the sense that the effects it teaches about also appear with laser beams and other many-photon coherent states, which you don’t really need QM for, even though QM provides their ultimate explanation. But whatever: it’s fun!) Piotr has lots of other great stuff on his website.
