Javascript canvas- is there an easier way to do it?

I want to work with HTML5 and the canvas tag, but without a interface like Flash provides animation is tricky. Are there any WYSIWYG interfaces for the HTML5 canvas? I saw that Adobe now has software that converts Flash to canvas, but the price is开发者_StackOverflow社区 too high.

You might want to take a look at Apples iAd development tool, iAd Producer, since it's designed to do HTML5 advertising and animations. You'll need a Mac, of course.
