Having read 'Atlas Shrugged', I recommend that you play the game 'Bioshock'. The priciples of the underwater city of Rapture are those proposed by Rand - and taken to a logical conclusion. As the framework for a physically gorgeous game, it makes the play experience delightful. That the plot of the game is also top-notch just adds frosting to the 'win' cake.

If you don't have an xbox 360, 'Bioshock' is frequently sold on sites like Steam for $20 or less.
