Years ago I was advised by  an electromagnetic compatibility expert to 
orient adjacent leaded ICs in opposite directions, ie, rotated by 180 
degrees, so the radiated fields from the current loops formed by their 
power and ground leads would tend to cancel each other. I don't know if 
anyone has ever taken his advice, or how useful it is now.

Following up on Inge's quote from Einstein (which I hadn't heard before), 
Paul Dirac said, 'It is more important to have beauty in one's theories 
than to have them agree with experiment.'

If it's not beautiful, it will prove to have little importance.
