What if restaurants and waiting rooms had scratch-and-sniff walls?  So while you are waiting to see your dentist, for example,  you could go around the room and scratch certain parts of the wall and smell different things. Is this totally impractical, like a nose hair trimmer that simultaneously scratches your chin when you use it or a toilet that plays Neil Diamond’s “America,” when you flush it?

Disclaimer: I’m not sure what my deal is in writing “today” in the title of these last two posts, cause it implies that I may be doing this everyday, and I won’t.
