title: iOS based OpenGL ES programming
body: <p>I need to find resources for learning openGL ES for the iPhone.</p>
  
  <p>I've already watched Brad Larson's awesome videos and I'm downloading the advanced videos from apple now. </p>
  
  <p>I know a lot about iOS programming but am clueless on OpenGL, so resources that don't assume I already know openGL. </p>
  
  <p>I want to learn a majority of the OpenGL capabilities, but my major goal is to be able to manipulate an image based on the touch locations. More specifically I want to create a water ripple effect that follows the users finger. </p>
  
  <p>I know there are many equations on StackFlow that implement this, but I'm lost when it comes to finding out how to use them.  </p>
