Inverted Colour display on OSX

I love that I can hit ctrl-opt-cmd-8 on my Mac and it inverts the colours on the display. It’s an accessibility feature that can make it so much nicer to use in certain circumstances and situations such as low or bright light or when my eyes are tired. Want to edit your document with white-on-black for a change? Just hit the magic buttons. It’s also a great practical joke to play on Apple fanbois to make them think their computer is broken...
