Here's the idea - First day of class, show up with a Mac laptop and a projector. In addition to the routine discussion of syllabus, grading policy, contact info and on and on ... have each student come to the front of the class and capture their likeness in Photo Booth - with you and the rest of the class watching and participating. Limit how long they have, but encourage them to explore the right side of their brain and create an "interesting" image. What you end up with is funny photos of each of your students, that will help you to remember their names (e.g. a semester seating chart) and help your student begin building a community.
