title: Animate object along a drawn path?
body: <p>I recently downloaded the sample application, GLPaint from apple. This app showed me how to implement drawing, but now I would like to animate a image over the drawn lines. Similarly to how the application "Flight Control" works, I would like to be able to draw a path for an image and then have the image animate over this path.</p>
  
  <p>any ideas?</p>
