Backlight - Mobile phone torch lamp combined with screen backlighter. Dual mode provides a time controlled torch lamp and also a backlight feature, for handsets supporting multiple apps, which temporarily disables a mobile phone's standard screensaver allowing another application's screen to continue to show on the display. The timeout can be quickly changed
Banner - The old UNIX program banner was used to produce huge ASCII-art text banners that filled the whole pages with as few characters as possible. In fact, this stupid little program was responsible for a lot of rain forests being devastated back in the 802s when the IBM line printers where common...
Blinker - The midlet either paints a black or a white screen. Switching happens when any key is pressed. Usefull? I don't know... maybe? (perhaps when stopping a buss in the dark!? or some sort of signalling)
