title: Creating a color halftone effect for images using JavaScript
body: <p>Would anyone be able to tell me if there is a way to apply a color halftone effect to an image using JavaScript and without using WebGL. I need to create it so it can be used across multiple devices and browsers. I have found this but its using WebGL: <a href="http://evanw.github.com/webgl-filter/" rel="nofollow">http://evanw.github.com/webgl-filter/</a></p>
  
  <p>Would I be able to use three.js or processing.js to achieve it?</p>
  
  <p>Any help would be very appreciated.</p>
