Visual communication is carried out through visual aids. The evaluation of a good visual communication design is mainly based on measuring comprehension by the audience, not on personal aesthetic and/or artistic preference as there are no universally agreed-upon principles of beauty and ugliness. Excluding two dimensional images, there are other ways to express information visually - gestures and body language, animation (digital or analogue), and film. Visual communication by e-mail, a textual medium, is commonly expressed with ASCII art, emoticons, and embedded digital images.The Eye of HorusThe term 'visual presentation' is used to refer to the actual presentation of information through a visible medium such as text or images.

It is said to be a representation of an eclipse, as the corona around the pupil is like the corona around the sun during a solar eclipse.
