title: how to create a particle system on iphone and retain the created particles?
body: <p>I need to create a particle system and retain the created particles. I need to shake / move the created particles with the iphone accelerometer. Also, the number of particles needs to be very high (I need to show sand!).</p>
  
  <p>I do not have any OpenGLES programming experience.</p>
  
  <p>After initial search, I found Cocos2D can be used for particle generation. But there is no way of retaining the particles in the CCParticle system. As a work around, I tried creating many sprites at the end of particle generation and shown them as particles. But moving few number of sprites with accelerometer drops the frame rate considerably.</p>
  
  <p>Please suggest how this can be achieved and whether I should look for some other framework or if some kind of similar demo code is available. </p>
  
  <p>Thanks,
  Swapnil</p>
