Hey Alan, thanks for all those ideas, very valuable! I’ll definitely take you up on some of those, esp. Getting ppl in my network to interact. It worked really great last year when I had rhizo14 folks respond to my students’ blogs. They were all starry-eyed over it (well, the ones who wrote good blogs and got good responses :))
The closeup photo thing – I am pretty sure the general idea of that came from #clmooc – i really like the shadow idea, too, though. Maybe since they’re working in pairs, I could ask each to do one of the photos… And maybe folks from my social network could respond with guesses as well 🙂
