title: Add Fisheye effect to images at runtime using OpenGL ES
body: <p>my situation is that i receive different images from the server onto the iPhone client.</p>
  
  <p>what i need to do is to add a Fisheye effect to those images.</p>
  
  <p>what my hallucination is that i can build a dome object, then attach images to it as they come to me.</p>
  
  <p>if anyone can give me any pointers to the right direction i'll be thankful.</p>
