The symphony water fountain is a sound activated water fountain where the water dances along to any accompanying sounds and music. In theory it sounds pretty cool, but unfortunately after watching the video it looks pretty naff.

The Symphony consists of 13 individual water jets, each of which can shoot water at 3 different heights (by the looks of the video). So when playing a nice tranquil song you and your guests can relax to the calming sound of dancing water, either that or your guests will just just laugh at you for wasting your money.

Further info and video over at Takara (sorry).
