For some you'll find it useful, others not so much, but I bet we can all agree: This app is straight-up genius. Based on the RoadSMS app for Android, this application allows you to text and walk safely at the same time. Using your devices camera as a live background for the keyboard, you can easily see through what you're typing and be sure not to bump into the innocent onlooker or the clever trap of chewed gum on the ground, ready to strike. 

Despite the strange scenarios you can come up with as uses, this application is certainly impressive, as Windows Mobile is not exactly known for smooth video playback, much less from the camera. Watch the video above for a demonstration, or go here to download.
