For some laugh out loud fun with your audio system sample the many twisted effects you can get with the Alesis airFX digital effects unit.
Simply connect the airFX to any line-level sound source and speaker system. Then move your hand (or any other body part for that matter) through the invisible 3D sphere. When you move in any direction; up or down, right or left, or in and out, the sound gets twisted in an infinite number of ways. The slightest movement of your hand tweaks the tones of the ultra-modern DSP system and turns your tunes inside out.
