While Microsoft has rallied the troops to build the ‘Ultimate Windows 7’ application, I find it quite ironic that Google Chrome in my humble opinion is simply that - ‘The most awesome Windows Application’. In further demonstration of it’s prowess, Google has release 50+ Chrome Experiments, showing the future of the web and what is and will be possible with HTML 5 (Canvas) and JavaScript.

My jaw is still on the floor where it collapsed onto after viewing just a couple of these demos. I mean, heavens! Ray tracing and real-time physics in a browser? Goodness!
You will need Google Chrome or Firefox 3.5+ to view these. Do enjoy!
