LAVA2 - Screen Designs and Backlight Control for the Newton. 21 day free demo This is release 2 of Lava, a compact and complete solution for making the backlight on the Newton function much more effectively. This is what it does: Turns the backlight on when the Newton is turned on. Backlight switches off after a period of inactivity. Backlight automatically switches back on when you tap anywhere on the screen. Animated screen designs can be drawn during system inactivity. All settings are completely under your control. By not making you fumble with the power switch every time you want the backlight on, Lava makes timeouts of 15 and 30 seconds completely usable, thereby extending the life of your batteries and the brightness of the backlight itself. For Newton 2.0 or newer. Takes only 14K of storage when installed.
