Making a Xylophone

One of my friends at work just celebrated the first birthday of his son this past weekend. We built a xylophone out of cherry, popular and electrical conduit tubing for him.
All the tubes had to be cut to the right length for the correct note. There are some that are a little off but overall they are pretty close.
Here is a picture of the backside. The back plate is made of 1/4" popular that was "stained" with acrylic paints. The cherry body is just oil with mineral oil. Under the four pads on the back are screws that hold it on.
This is a picture of the bottom side with the back cover removed. You can see the turnbuckles that tension the fishing line that strings between the two bridges on the front side.

And finally what you have been waiting for.......the video of Kristen playing it.
