Google launched the public beta of Google Web Designer. Web Designer is a desktop application for creating interactive HTML5 sites and advertisements. The tool was built for the purpose of creating advertising units, but it can be used for building webpages and other non-advertising materials.
Web Designer allows you develop pages that contain drawings, animations, and 3D objects. Web Designer includes galleries of pre-made objects to drag, drop, edit, and compile in the creation of animations. The animations come together through a layered timeline.
I gave Web Designer try this afternoon. It is not a tool that most people will master quickly unless they've prior web design experience. Fortunately, Google has produced a lot of tutorials on how to use it. You can read tutorials here and watch tutorials on YouTube. If you decide to try Google Web Designer, you will probably want to try it on a screen larger than 13 inches. I tried it on my 13' MacBook Pro and would have liked to have some more screen space in which to work.
Applications for Education
Using Google Web Designer could be an excellent progression for students who are ready to move beyond the basics of building webpages in Google Sites and other free website builders.
