Computer Art - The biggest optical illusion source you will ever see.

No matter how much a person may create designs or try to create a graphical image, it will never truly be 3-dimensional.  And so, we have to play with our eyes to make the image appear 3-D through various tools.  You might not think what you see in front of you is truly flat until you turn your gaze at the side of your monitor where the screen is just a sheet. And yet, there are plenty enough programs and styles to design the very windows we use, the sites people visit, or the images, videos, or games people view and play.   Everything from paint programs, to photoshop, to flickr (which will be fun to learn in the future), to video editing, to animation, and finally web design (which I may discuss in its own topic); most of these still take the same artistic creativity while at the same time, some of them may use scientific thinking.
