Large pole with computer controlled vibrating tip. When held to a pane of glass, it weeps through frequencies until it finds the natural resonating frequency of the glass, alerting the pole-bearer, who can then turn up the energy, thereby shattering the window.

If that fails, pole can be used to smash in window.

Just so long as you make it look like this. http://mlb.imageg.n...MLB2-1469581reg.jpg

//weeps through frequencies//
A crying shame. Also, a single light tap would cause the glass to resonate at its natural frequency, which could be measured.

Only for glass? I want to be to wave it around dressed in a silly wizard costume, and it to cause things to magically happen with harmonic frequencies. +

I've got two for you:
1. The guy with a 15ft pole inside a 9ft house that manages to not break the window, and
2. The choir singer from Krakow that keeps singing out of key.

You choose.

Such a pole could be used to find the resonant frequency of a large solid non-glass object - for example, the Washington Monument or Ayers Rock. The object should then vibrate sympathetically and loudly. One could then use a microphone attachment to convert spoken words or music into permutations of the resonant frequency, and use the object as a giant amplifier.

You gotta love self-adjusting resonators.

And where would you carry such a device? You would want easy and central access to it with either hand. Perhaps behind a zipper, or buttons.

One possible problem. I suspect that most objects will change their resonant frequency slightly as the amplitude increases.
