As for that squiggly code thing you mention, my phone does have that capabilty, as do many phones these days. I tested it out on your site and it works like a charm: I can read your blog while riding the train or bus. I suppose that might be a useful thing for students who have no computer.

Thanx for the edublogs.org link

Something I hadn’t thought of when I got it a few months ago, is QR code capability (is this Japanese? I don’t know what the English for it is): it’s a small square with squiggly lines all over it: you hold your phone’s camera up to this square (on flyers, adverts, magazine pages, even websites) and click and it gives you cell-phone access to the website (I think). I wish I’d got it, altho a quick informal survey of my students and children revealed that only a few knew about this capability and even fewer thought it was valuable or useful (or knew what it could do!), but there is a wide range of awareness of such matters amongst the Japanese college-going population, and it seems the ones I teach are amonst the less-”wired” (sniff).
