Today's Google Doodle extends Olympic fever to the desktop and to Google+ circles. But for developers what is interesting is the way in which it uses canvas to such good effect.
I have a feeling that lots of people are going to be spending a lot of time improving their personal best scores and sharing them with their circles on Google+.
It may just be the boost required to make Google's social network a serious contender in the race with Facebook.
To access the Google Doodle just do a search on Google on August 7, 2012. Hopefully it will be added to the Google Doodle Archive in a playable form, or even open sourced so that we can all learn more from it.
