Tag it
Here's a cool new app from a sister team of mine: http://www.microsoft.com/tag/
First, download the free app to your Windows Mobile phone (takes just a couple seconds).
When you run the app on your phone, it starts the camera automatically. Just aim the camera roughly at the tag you see on this web page. That's right, just point it at the computer screen. Tag will recognize the object and take you to the URL I have buried inside!
The cool part is that it's easy for you to create your own tags. I did one in about 5 minutes.
