If you have a PSP or a PowerBook or perhaps an LCD monitor on your desk that has a stuck pixel, it's probably driving you insane. You'll probably try anything to fix it. Of course you've tried gently massaging the pixel back to life. When all else fails, there's one last resort. Someone has created a video that flashes through RGB in rapid succession. The theory is that all that flashing will cause the pixel to become unstuck and begin working. I've read elsewhere it has worked for some although it took a couple of DAYS (looped). Give it a try, post your results and whatever you do, don't stare at it!
