How can I make the cards look like they are spinning

"""Spinning reel test. Small working example.

   How can I make the cards look like they are spinning,
   like in a real slot machine? There will be 5 reels
   in the game eventually.

   Also, how do I make sure the card images do not eat
   up memory when thet are re-called time and again?
