Japanese firm K Opticom is paving the way for a relatively untouched sense in today's gadget world - smell. Trial units of the "Kaori Web" system will be placed at K Opticom's internet cafes in Japan until the end of September. But what is the "Kaori Web," you ask? See a picture of a flower, smell a flower. See a picture of waffles, smell waffles. The "Kaori Web" helps some realize their dream of having computers produce scents, to immerse them into a new environment finally covering all five senses. Or hackers will just use it to make some websites smell like a dog exploded.
