Targelin is a method of drawing detail in the most important parts of a work - the more important, the more detail - but the purpose is not to point out the most important part. Instead, they are substituted for by large triangles and the undrawn portion gives off only an aura of what is there. The undrawn parts are, in other words, imaginary symbols. At the beginning, small triangles are gathered as pixels, transmitting information as symbols. Those triangles gradually grow larger and change from determined symbols to imaginary symbols, this time starting to receive the information. It works as an auto-regulator of the imaginary portions, starting with requiring slight guesses and gradually progressing to causing an amplified level of imagination.
