Thank you, Timoteo and Miss Nancy.   The aura around the lights on the wall are modeled as a bubble surrounding the light.  It's important to smooth off corners in order to use the double edge blend node method, because it emphasizes eccentricity - tight bends and sharp corners are more visible than gently curved areas.  The monitor aura is much the same as the aura for the block lights.

     I've gotten the nodes neatly arranged and renamed for each type of material;  now I need to apply them to the other lights/emitters/aurae, with appropriate phase shifts.  I'll post material room screenshots as I get them done.
