Let's face it Pete, some of the levels of creativity shown here transcend what one learns to expect in the run-of-the-mill classroom. In fairness to the lecturer, he does have a syllabus to work through, and in fairness to the student, any extra marks he gets for originality, even from a sympathetic professor, are unlikely to outweigh marks lost in failing to memorise syllabus material.I leave you to imagine how the finest minds allocate their resources.  ;-)
