ConfigurationOfAthensSketch loadDevelopment. AthensSketchBrowser open. ----------------- This is a simple playground for Athens drawings. Just subclass AthensSketch and define your own sketch drawing in the #drawStepOn: method. It provides basic frame based animation (play/pause/stop). Open a player with ASketchExampleColors openPlayer', or a simple viewer morph with ASketchExampleColors openView (start and stop rendering from the morph menu) The AthensSketchBrowser lists all defined AthensSketch subclasses. (Basic examples from package AthensSketch and some more examples from package ASketchExamples). You can step through the list of examples, start and stop the drawing, or view and edit the drawing code. It is great that we have now a vector based drawing API. The (old) Canvas API is already great for pixel based drawings. A rich API and many good things if you discover it. And Athens is aÂ addition that can increase our possibilities. There were some questions about Athens, what it is and what it is used for, maybe this helps. Â nicolai

Thanks for your answer Damien, but there is not a save button in the version installed from ppa repository, at least not in the version for ubutnu 14.04. I just realized that the button Export Settings do that job.
