Good arvo from Sydney, Australia, where it's beautiful even in the dead of winter and the people use contrived abbreviations for literally everything. I kid, I kid. Australia is great, and the vegemite is even greater. I've spent my winter internship (also called a "summer internship" for my compatriots above the Equator) working on the Google Maps API for Flash, which was released back in May. If you're like me, you might think that Flash is a tool for creating amateur cartoons of questionable legality after school. Friends, I assure you -- it's so much more.
The interface for the Flash API's Directions class closely resembles that of the JS API's GDirections class. You still create a Directions object, optionally listen for load/fail events on it, and then call the load() method with a directions query. The Directions object contains all the response information as Route and Step objects, also like the JS API. The awesome thing about Flash is that you can then include all sorts of animations and movie clips to complement the directions in your application. Consider the following application which uses a penguin to show you how to get from the Alamo Drafthouse movie theater to Waterloo Records in Austin:
