Now this is pretty cool. WikiSaver released an application recently that acts as a type of interactive screensaver. The app can be used when you're not charging your device by simply selecting the WikiSaver icon.Here's how it works:
"When plugged in, a random page from Wikipedia shows on your BlackBerry screen. If you click the trackpad/trackball or hit the back button the screen disappears."
If Wikipedia doesn't tickle your fancy, there are plans to include other similar websites to the app so you have even more options.
