If you’ve got a Windows Phone running HTC Sense 2.5, you can “confuse” the weather demo that is accessible from the Home tab. In this video, submitted by Multimedia Freak, if you rapidly tap your finger, you’ll get combination animations…like sun and rain at the same time, or snow and rain. I tried this and couldn’t get it to work, so perhaps it only happens on certain ROMs. Does it work for you?
