Exhibition: Show/Hide background in Time [webos 2.1+] 7

This tip is only for devices running webOS 2.0 and higher

When you first load up Exhibition mode in webOS 2.1 or higher, you are presented with a screen that looks like the typical webOS lock screen with the time on a black screen, just without the padlock icon to unlock the phone. However, if you are into a little more color and want more than just a black screen, you can tap anywhere on the screen to display a blurry picture of what appears to be a field of green and a blue sky.  Want to return to the black screen?  Just tap on the picture again. Here's hoping that HP will allow us to select our own picture in the future, just as you change your phone's wallpaper.
