I must admit, being seriously lateral thinking and totally multi-focused (ok un-focused) I am quite happy to follow a thread wherever it takes us. As far as I am aware that is exactly what brainstorming is about. I am glad there is a forum like this available where experts and novices can exchange ideas. I think it is just as helpful to mull over bad ideas as it is good ideas! So please go ahead and add your 2c and "singing in the bath"
