LESSON 1
About the viewer:the RED filter goes on the left eye, and the BLUE filter goes on the right eye. For those with a third eye: that's where the middle one goes.

Now, without the viewer, look at my left hand.
You'll see three blue and three red fingers. The red ones stick out more to the right. Those are the ones that your left eyes sees. The blue ones are seen by your right eye. 
Put on the viewer and see how the mind assumes that since my hand is further to the right for the left eye than it is for the right eye, the hand must be closer to you than rest of me.
And my table with the viewer on it is obviously closer than the text you're reading.

LESSON 2
Here we see an anaglyph artist at work, using very basic tools.

THE MATERIALS
First you need a 3D-canvas. These are available for free all over the net. Try here for instance:
http://www.freestuff.ana/3Dcanvas.
Make sure the canvas has a solid base, and is big enough to give you room to move.

Next you need the paint. If you're a novice, don't go for all the colors, but stick to basic red and blue.  Go to a well-stocked 3D-store and ask for  ANAGLYPH MULTI-CHANNEL LAYER®. This is by far the best brand out on the market and easy to apply. You can also order them at HOLLOWPIXELS.COM.

Tomorrow we'll move to the next lesson: 
HOW TO SET UP SCENE.

For now:
Go to TOMORROW.
Go back to WHERE YOU WERE BEFORE YOU WERE HERE.
