I’ve created a new Maps screencast that covers the use of the display_point parser function of Maps as it works in version 0.5. I’m assuming you have seen the display_map screencast before you watch this one, although the basic syntax is covered again quickly.
I’ve also made the projects for both screencast publicly available. If you have wink, the application I used to create the screencasts, installed, you can simply modify the projects, add your own stuff, and render your own version. I’m hoping some fans of Maps use this possibility to improve the screencasts and help their fellow Maps users.
