Google Web Designer
Today I've come across a nifty little tool that's still in the beta phase, but has great promises. It's name is Google Web Designer.
Currently there are several applications that deal with HTML5 animations, but most of them are just not up to it, or cost too much for the lone developer. But here comes Google with it's Web Designer applications.
While it's true, that it currently has many bugs, and not all animations work in every browser, but it's still in the beta phase, however, agencies and marketing division who use Google Ads can find a great tool creating display ads.
I hope that as the project goes along it will evolve into a superior tool for html5 animations, finally replacing flash as it is...
