If you own an iPhone, then you can turn it into a Snow Globe at this url: http://www.popart.com/iphone%2Dsnow%2Dglobe/
Go to the page and then turn your phone on its side and then back up again - and you have a snowy snowman!
Unfortunately the effect only works on the iPhone, it won't work on your PC or laptop. I tried turning my monitor on its side and than back again, but no luck.
