Street View Snow

Here is another Christmas themed Street View application.

Everyone Deserves a White Christmas is a neat application that allows you to view any Street View image with added snow.

To create your own white Christmas you just need to add an address to this app and watch as some animated snow falls upon your chosen scene. You can then share your wintery scene via Facebook, Twitter or e-mail.

There's something very clever going on under the hood of this app. As the snow falls it actually settles on the solid objects in the Street View image and somehow knows not to settle on the sky.

I can't work out how the snow detects solid objects in the image. I guess the app must somehow detect the color of the pixels in the image and, for example, avoid settling on the parts of the image that show the sky.
