In the past year, I’ve really become fascinated with QR codes, that’s quick response codes.  These little crazy square thingies are popping up everywhere—even on t-shirts!  Did you know they’ve been used in Japan for about 15 years. Who knew?

I’ve gathered up some resources here that I use in professional development workshops with K-12 teachers and higher education faculty.  So, give a bunch of these a go.  If you know of others, be sure to leave them in the comments so everyone can get them.
