Smell-o-vision???

Something that I learned from this article is that a japanese team of researchers are researching how to accomplish making a Television that allows you to smell the object on screen.  Another thing I learned is that people have been trying to make a smell-o-vision for  over 50 years now. I also learned that the smell-o-visions are going to deliver the scents with pinpoint accuracy, having the area where the object is, being where the scent is. Something I like about this article is that its sort of funny and weird. Another thing I like about this article is that it shows where TV's are going.... A question i have about this article is what if you watched a documentary on sewers?
