There are a few ways to watch the 2012 London Summer Olympics online, but this is how I do it:
Step 1
Go to http://tunlr.net/get-started/

Choose your operating system and follow the instructions on the page.
Step 2
Go to http://www.bbc.co.uk/sport/olympics/2012/live-video and click on the "Live" link.
From here you should be able to choose and watch the live streams of the Olympic games!
Before

After

I'm not sure how long this method will last, but I hope it works during the duration of the entire 2012 Summer Olympics.

Ever since I started taking strength training seriously, I was bitten by the Iron Bug. Then it burrowed under my skin and laid eggs in my heart. Now those eggs are hatching and I... the feeling is indescribable.

Hi John,
Thanks for the tips but you probably know that Tunlr does not work anymore for Netflix. You can try an alternative solution called UnoDNS
