Nah...I think it's >BRILLIANT!<
Think of the advertising possibilities. You can work a similar device for the ladies room as well.
Awhile back I was kicking around the idea of an audio - or possibly visual advertisement that would be triggered by an IR/motion sensor in bathroom stalls.
FWIW a dozen or so years ago I came up with prototype "Greetings in a Can" where you'd give someone a soft drink or beer can for a holiday gift. When they poped the top they would hear a message you recorded.
I also came up with battery operated fish for people who don't like the problems associated with real aquariums. A variation actually made it into production but it wasn't me version....sigh.
Crazy ideas but I bet yunz would make a gazillion bucks!
I love capitalisim.
Where can I get some of those electric pet fish?
