If it's a toss-up between making music or love instead of war, most people will go for love; however, if pressed I guess they'll make music. That's the target audience for the ravezooka, a mashup of the household bazooka and the deadly electric guitar - an ultrasonic range detector adjusts the frequency range of the sound it plays, while a movable trigger handle changes the distortion of the sound. Volume is managed by a simple knob on the side. An LED on the front gives a rough idea of who you're targeting, while the sounds themselves are triggered on an attached computer by MIDI data from the ultrasonics. If you're having trouble visualising it, there are videos of it in action on the project page (linked to below).
