    I notice the Sandbox contour line and colors align exactly in the center of the sandbox, but towards the edges they get off-center by about 2-3 inches.

    First, try re-running the calibration procedure and collecting more than a single set of tie points, i.e., continue collecting after the crossed lines snap back to the lower-left corner, and the red crosshairs following the disk show up. Also, try collecting points both from above and below the usual sand surface.

    If that doesn’t help, and the red crosshairs do not follow the disk well around the edges of the box, you might have to run per-pixel depth correction on your Kinect to reduce the non-linear distortion of its depth image.
