IBrian and Theresa write, "I have enclosed a picture of what I think “could” be a vortex in our living room. I’m not sure, but I don’t know what else it could possibly be. It was taken in April of 2003 for my son’s birthday party. He is the boy just to the right of the object in question. It was rainy outside, pretty normal cool spring rain, in the middle of the afternoon. We were using a Nikon digital camera. I have heard that there are cool spots where a vortex may appear. Hard to tell if there were cool spots, we had the front door open to let in a cool breeze. The house we live in is military base housing built in the 1940’s."
