screen pixel tester

This is a simple program that cycles through colors, so you can look for stuck or dead pixels on your screen.

Before you press the link below:
* You cycle colors by clicking on the background (body)
* Set your browser to fullscreen (i.e. in Google Chrome you press F11)
* It goes on forever, so pressing back is not very useful, maybe open the link in a new window/tab?
