It started snowing halfway through the first lesson this morning. The kids were so engrossed in their stop motion animation work that they *didn't* run to the windows, shout, make a fuss, get distracted etc and many of them didn't even notice! And second lesson the next class came in high as kites and somewhat soggy, and then got interested enough in binary and game states that they settled down and just got on with the lesson.
Weird!
