Thank you a million times for this! This is so awesome.
I see a lot of replies describing this as "silly", which it certainly is, but it can also be very useful for some. For me it brought back the only feature I've missed from my decade old Nokia feature phones: being able to shut them off completely for the night, and still have the alarm wake me up in the morning.
It's also really great if your battery runs out, and you leave it to charge. Now you don't need to worry about forgetting to turn it back on again. Awesomesauce.
I was already damn impressed with the OpenGL-tweak app and the dmesg/logcat bootscreens, but this is, to me, even more amazing and awesome, can't thank you enough Chainfire.
I realize actual brightness changing would be a hassle, but as you've stated in the thread, for AMOLED-screens, simply changing the color from white to a darker gray would achieve the same result. I'd love to see a feature like this, nothing fancy - something like "use darker graphics" when installing the system files etc would be appreciated. Also, it'd already help immensely, if there was an option to disable the logo (brightest part of the screen, at least for me) from being displayed.
Again, great app. Even if you did code it as more of a joke than anything else, it's really useful for me at least, and I'll have you know I'd gladly have paid double the price I paid for it. I ended up just sending a small donation instead through the link in your signature, instead.
Keep working on awesome stuff like this from time to time, the Android ecosystem needs a dozen more developers like you!
e: dammit, missed the last few pages of the thread, I see the images can be modded quite easily.
e2: quickly batchedited together a darker imageset, all images (except for the check-marks, I didn't like how they turned out and couldn't be bothered to do them by hand at 2am) are at 50% brightness, and I quickly masked the text from the logo and removed the background. Install through CWM (install script stolen wholesale from ironheart) or manually copy the images over.
It doesn't look great but gets the job done, if I have a couple of minutes free tomorrow I'll try and whip up something a bit more decent.
Here's a rough idea of what it looks like:
