Last week I posted about the end of Flash, one of the thing I regretted was the loss of a tool to teach animation.
This week I noticed Wick: The Internet’s Free and Open-Source Creation Toolkit. This  works best with Firefox and Chrome. It make javascript animations that can be exported as a webpage. I’ve put one in the iFrame below.

It looks like you can do a lot of cleave stuff with JavaScript, byr the editor supports the use of motion tweens and clips that can have their own timelines and tweens without any scripting.

My skills in this department are limited, but if you look closely you will see the person in the animation is moving his arms and legs. They are a clip.

The flash vacuum is being filled before it exists.
