The most apparent example +of this is the game loop. The game loop runs at 60 frames-per-second +and uses fixed timestep updates. Those that have read +,(anchor [Fix Your Timestep] + "http://gafferongames.com/game-physics/fix-your-timestep/") +will know that this decision is a good thing.]) + + (p [Perhaps the most important feature of guile-2d is the ability to +do “live coding”.

Using the great +,(anchor [Geiser] "http://geiser.nongnu.org/") +extension for Emacs to connect to the REPL server, one can modify +their game as it is running.
