A while back I stumbled across the Sardines competition organised as part of the Festas de Lisboa. The concept is really simple: download an outline drawing of a sardine and then fill it with whatever springs to your creative mind. We thought it might be a good exercise for the students, to get them experimenting with pattern and design.
There was quite a lot of productivity and creative work produced --but unfortunately none of it came from my end of the room. I only managed to doodle two sardines before duty called me elsewhere, and they were both a bit naff. But here they are, just for the sake of completeness.
