title: Animation in C++
body: <p>What are ways to draw animations in C++? GDI+? OpenGL? Would you recommend a class pattern in particular to get the drawing and redrawing done? </p>
  
  <p>Do you know of any open source project where animations are made so I can take a peek at the code?</p>
  
  <p>Where would you start if you wanted to code geometrical animations? Do you know of any good libraries? Post links to tutorials and any other interesting information...</p>
