I don't think bringing in issues of "Scientific Proof" with the streaming icons is right. For one, consider, if you had one would you like to hand it over to a Scientist to perform analysis on?
It really does not good anyway, because even if a link on the internet is provided as proof, containing a photo, testimony, or even slight analysis on the icon, it would never satisfy.
All I can suggest is anybody who doubts, to go see one for yourself. Try to find one at a monastery.
I had the HONOR of holding one in my hands, and I fully believe it was streaming. Before that I was really iffy if it was happening and thought it could have all been a hoax. I am 100% positive it was streaming. The wood on the back was aged and old (probably from years of having incense near it). The paint was not tampered with. All I have is my testimony, and can tell anybody, "if you don't believe it, go see it".
