title: XNA 2D objects in 3D environment
body: <p>I'm currently working on a 3D game in XNA 4.0 and I have a 3D environment, a controllable character and a camera that follows the character up and running. But now I would like to draw 2D images in the 3D environment.
  The reason for 2D images is that I want Legend of Zelda Windwaker like explosions.</p>
  
  <p>Can anyone give me recourses, advice or code snippets (in case it's really simple) on how to build this?</p>
