You can view a work of art and feel as if it is sinking you into another dimension... Another world. This is because there is depth to the picture. There are shades and distances and colors that all contribute to making a flat surface "appear" 3-D... Yes, this is the illusion of space. The flat piece of art will always be just a flat piece of art. There is no true depth to it and that is the MAGIC of the illusion of space! This is what every artist should strive to achieve because it is the first step into making a GREAT piece of flat art!

Here are two examples of the great illusion of space painted in the Sistine Chapel by the famous Michelangelo. The depth that can be seen is amazing. I personally feel like it is possible for me to touch, grab, and hold on to the man's held out hand.... Just amazing.
