i highly reccomend this! instead of having OSX control my backlight (which dims in and out because of either light or non-use)
i can keep my lights on constantly!
the only issue is that the latest release, 0.8.4, causes flicker while in OSX Leopard, so i recommend (as i saw someone else do the same) lab tick version 0.8.1 (no flicker in leopard!)
very nice and versatile tool
