Google Web Designer: Production-Ready Tool or Toy?
Google Web Designer is a graphical design tool for creating HTML5/CSS3/Javascript banners and advertisements using animations and 3D transforms. Using their graphical tools such as drawing, text, and 3D objects, you can animate these objects and events on a timeline using keyframes.
GWD is clearly not designed to create fully-fledged applications or entire websites, but rather banners, popup ads, sidebars, animated buttons even, with a strong focus on projects for Doubleclick and AdWords campaigns.
