Back in June, Google's advertising arm put up a blog post, letting us know it was about to release an HTML5 development tool, called Google Web Designer. Well, it's just arrived today, per a post on Google's own G+ account, and it's available in beta as a free download. Throughout, the tool appears to cater to both seasoned coders, as well as amateurs looking to try their hand at web design (or looking to get it done on a budget). For instance, while you could tweak the code by hand, there's also an option to let Google focus on the HTML5 and CSS3 grunt work while you focus on... the easier stuff (whatever that is).
Likewise, you can animate individual elements using layers or, if you don't know what you're doing, you can just animate scene by scene and let Google fill in the blanks. Additionally, you'll find a suite of 3D rendering tools inside, along with illustration features. As for monetizing your site, Google Web Designer naturally integrates with Google's own AdMob and DoubleClick Studio -- no surprise there. At any rate, if you feel like getting your hands dirty with code, you'll want to hit up that second source link below.
