Water through a wall

A client of mine had a retaining wall built along the back of his house and he left a 5 or 6 foot wide hole in the wall for me to put a water feature in. Sorry about the video quality...I kind of just wanted to see if the video feature from my phone (I've only dropped my phone into a pond once, so far) could make it to my garden blog.
As for the noise at the end of the video clip...my wife, Donna asked, "is that your stomach?" No, it isn't! Ha Ha Ha!
