Painting, a form of architecture, drawing and sometimes computer art all makes visual art an outstanding form of art. Being two dimensional in any form makes it a visual art, it makes art a little confusing to those who do not understand it, somehow.
A connection of ideas, a chain of stories can be well said through incorporation of images. Joining them together to form one image that is sensible to anyone just after having a look at it is the main point being driven by artists on visual art. It is a rare form of art that is exploited by a few, we appreciate such.
