HTML5/Javascript Educational Apps/Ebooks

I have been exploring options for creating interactive educations apps or ebooks using an html5/javascript based framework rather than using a native iOS, Android, or proprietary iAuthor type format. 

Still early days in this project yet, but some interesting frameworks to follow up on are:

Cloud based ebook authoring and delivery tools that use html/javascript

• Habitat by inkling - has a great versioning and team workflow backed by SVN
• Aerbook - very extensible using javascript based widgets

Interactive app/gaming frameworks

• Impact.js
• Lime.js

3D/2D javascript frameworks

• Three.js
• Create.js

Desktop animation tools

• Sencha Animator
• Hype
