How odd, but fun! I can make all the magenta disappear without too much
trouble. Quite funny!

The green dot is strange. LOL!

I find a couple of things really fasinating.

1) The function and workings of our brains and eyes.

2) HOW does anyone come up with this kind of stuff?!!!

If you've ever spent and entire day in a 'green screen' studio, where EVERY wall is green, you'll notice how 'magenta' the world is when you leave it!
