Let's see the humidity. Anyone?

Finally hot and humid today. As I pad around the house I wonder,
someone must have made a picture of how humidity moves in a house.
One side of you feels sticky and clammy, the other doesn't but will
soon. Humidity must move around like mist except that you can't see
it, except when you see mist. I'd love to see a good computer graphic
of humidity moving around a room. It must move like mist, like
clouds. Let's see the graphic. Anyone?
