Angels, XForms and Messaien

This improvisation is a return to ethereal music which I haven't done for some time. I've actually got my head down in really concrete stuff at the moment - a crazily large and complex questionnaire which I'm coding in XForms (because QTI was crap). When doing something so prosaic and dull, I've always found a 'corrective' of some sort is required. So into the ethereal world of the uncertain and ineffable. And out of this balancing new things arise...

Which does raise a serious question... particularly for the poor sods who are going to be answering my questionnaire. Will we encourage them to have a 'corrective'? Where's the balance in e-learning?
