One of those orange smoke bombs one can find on life rafts? Excellent idea! Now, we just have to find a way to paint a thief using unwashable paint used to mark/destroy stolen money etc without painting the car interior. Strange, Q never had problems with such details...

The only catch is that I would be affraid to enter my own thoroughly boobytraapped car

Cheers!

P.S. Regarding the original sound blasting idea, aren't there simpler sine wave generators than empeg?
