My alternative to the post-it system: high-fives I teach a course introducing students to making plain webpages in HTML/CSS/JS. We haven't tried the group aspect yet, instead we have people pair program - one laptop between every two students, with them switching 'drivers' every 10 minutes or so, driver types while the other person narrates what's to be done and points out typos etc. When a pair reaches the goal for a particular task, I ask to high-five loudly. Not only does this help them get more comfortable with each other (they're complete strangers and only come together for this single day course), but it livens up the room a bit while giving me feedback and without being too threatening to those who are still working.
