title: Rubik's Cube OpenGL Implementation
body: <p>What is the "easiest" solution to code a Rubik's Cube with the following features in Opengl:</p>
  
  <ul>
  <li>"Camera" moves to let user see the cube from any point of view</li>
  <li>Smooth display of cube moves in response to user clicks when playing</li>
  </ul>
  
  <p>I started with a solution drawing the cube "Face by Face" but I am not sure it's a good solution (I am facing many problems ...)</p>
  
  <p>May be a solution "unit cube" by unit cube (27 cubes has to be drawn) is easier to implement ?</p>
