PowerBlinken is a silly Mac OS X application that allows you to use your PowerBook as some sort of lightshow by setting transition, fading and blinking intervals on your PowerBook's backlit keyboard and LCD display. It requires a PowerBook or MacBook Pro to function correctly.
The backlit keyboard is controlled with the controls within the "BlinkenKey" box, while the LCD is controlled via the controls in the "BlinkenScreen". The "Synchronize" button can be checked to have both the backlit keyboard and screen blink in sync. The gray bars on each side of the window measure the light levels detected by the left and right light sensors on PowerBooks.
The source code to the program is made available undir a public domain license -- you are free to do with it whatever you may please.
I don't know if the program is harmful, but I have difficulty imagining so -- I have certainly run it extensively on my PowerBook G4 without any adverse effects whatsoever -- never the less, let it be said loud and clear that YOU RUN POWERBLINKEN AT YOUR OWN RISK. .
The latest version is PowerBlinken 1.0. It requires Mac OS X 10.4 or later in order to run, and is provided as a Universal Binary. Source code is included with the application.
