I’ve come across this in a number of posts from my colleagues in  DPE.

Last night and I went to http://www.cuttherope.ie and played this game in the browser.

From an engineering point of view the interesting content is at http://www.cuttherope.ie/dev/ which explains how they went about porting this from
Objective C to HTML 5 and JavaScript.

“To do this, Microsoft’s Internet Explorer team partnered with ZeptoLab (the creators of the game) and the specialists at Pixel Lab to bring Cut the Rope to life in a browser.”

One of our UK DPE Colleagues Martin Beeby also talks about this at http://blogs.msdn.com/b/thebeebs/archive/2012/01/10/cut-the-rope-now-in-html5.aspx
