While I was cleaning out and throwing away some old junk, I came across some old promotional stuff for iSmell scent technology which I guess I picked up at the 2000 GDC. I saved it for humor value. The company (Digiscents) met its demise in June 2001, to no one’s surprise. I thought I picked up their SDK and documentation as well, but I must have thrown it out a long time ago.
There’s an article linked from that Wikipedia entry titled “How Internet Odors Will Work,” but I’m afraid that it’s too much of a low-hanging fruit for even me to make a joke.
Someone appears to have taken over the Digiscents domain, and is running a “digital scent technology blog.” (For a laugh, check out the Google AdWords at the top of the page.)
