Hi Keith,
I read about that aura and were looking for that, only found this artist
http://www.elmundo.es/elmundosalud/2...117727201.html but I know there are more and well known, great painters. Just telling you that my teacher also suffers migraine, it is horrible. I had a headache but from a cold, just an aspěrine and thats it. I hope you are feeling better, take care
