even open source projects for kids are moving to HTML5.
MIT Media Lab has developed a nice tool for teaching kids programming, Scratch.
Like lego blocks, where each program statement has a visual "block".
Arrange blocks, and this makes program.
At begging it was a portable desktop tool, and with Web intent was to move it to Flash,
as an interactive / "multimedia" tool.
Popularity of iPad has changed MIT plans, since it "must run there".
So it is now ported to HTML5. Nice :)
Scratch (programming language) - Wikipedia, the free encyclopedia
Scratch is written in Squeak, an open-source implementation of the Smalltalk-80 language.
(The syntax and runtime behaviour of the Objective-C programming language is strongly influenced by Smalltalk.)
