A cheap flashlight

It fills the entire screen with one of 8 colours of your choice. Selected by using the up/down motions of the directional navigation pad, or by simple finger-touch scrolling up/down.

Default is White (like most flashlights). But can be Grey, Blue, Red, etc. if the situation requires.

It's small, simple, yet effective. You never know when you might need to guide yourself through dark areas using your PDA.

note:  Simply double-tap on the screen to exit the application.
