If you have an iPhone or iPod Touch, you can now add any of the sinkerbeam sites to your home screen and you'll get a specialized icon instead of a mini version of the webpage.
Why would anyone care? I don't know. It's kind of a geek thing to do. But in a cool technology way.
Don't know what I'm talking about? That's OK - you won't notice anything different on the sites. You could always get one of these devices and see for yourself, but don't do it just to see the sinkerbeam icons. They look like the ones in the picture.
