This is a funny one. I was never a shadow writer until a friend asked for my help with a patent he was working on at the time. I didn't see much future in this patent but I didn't mind contributing my shoulder to help him push the load. By now he might have given up on the idea or have become a nouveau riche (I wish he did), however this page deals with my modest contribution to his effort.
I won't describe the technicalities of the proposed patent, it's his intellectual property; but the general idea was to have a warning mechanism (the car belt talks to you) in the car which tells you that you didn't buckle up (yes, I know it exists already, he insisted he had a more original design), and if you still did not heed the first warning - it prompts you again. Sure, there is always the possibility of a third prompt - electric shock, lethal injection, or a scream in your ear. I just provided a jingle, didn't want any responsibility for physical and/or psychological injury. That's me, big soft hearted. I just provided a jingle for the first prompt. AND for the second. AND for the third one, which actually is a 'thanks' message in case you did buckle up. Believe it or not, I actually enjoyed the challenge. Of course, in the end he chose something so ordinary and so not of mine that I felt insulted to the tips of my toes, but as the one that didn't pay anything for it - he has all the choosing rights.
Personally, I prefer mine (of course) and they are so short and nice (of course) that I must let the world enjoy them as well (of course). Don't be surprised, and hopefully neither will you be offended by the sexual undertones here and there, after all this thing is supposed to sell. Thinking about it, one could actually add a nice touch to the device by providing the user with a choice of different voices - male, female, or even 'other' (leaving it to your imagination?!?!?!...).
