Text copy wont work.

I really dont see anything new here. This is exactly the same stuff they have at Google books. Except now its in an iframe .

Flash implementations are obviously superior as of now.Also, try building a decent browser game in javascript and html5.

Actually games that don't involve too much motion tweening (think sudoku, tic tac toe etc.) can be done pretty well with js and html5.

This is old but this version of arakanoid was always pretty impressive.

Note it does cheat and use flash for SFX

Nope, it was just a thought. You're just going to be changing the innerhtml of DOM elements. Shouldn't be tough.
