Copyleft, copyright and just copy (ing)

Copyleft is a play on the word copyright and is the practice of using copyright law to remove restrictions on distributing copies and modified versions of a work for others and requiring that the same freedoms be preserved in modified versions.Copyleft is a license and may be used to modify copyrights for works such as computer software, documents, music, and art.

Copyright is a set of exclusive rights regulating the use of a particular expression of an idea or information. At its most general, it is literally "the right to copy" an original creation. In most cases, these rights are of limited duration. The symbol for copyright is ©, and in some jurisdictions may alternatively be written as either (c) or (C).

Copying is the duplication of information, or an artifact, based only on an instance of that information or artifact, and not using the process that originally generated it. With analog forms of information, copying is only possible to a limited degree of accuracy, which depends on the quality of the equipment used, and, if applicable, the skill of the operator.

Reproduction and copying that we change we can call REMAKE, but still in Art REMAKES made only talented workers without enough inspiration to create something new! Artist can use information to rebuild their own forms, but not copy it at all and call it their own art!

Or what do you think, can I call my copy (right) an art-work or maybe a masterpiece because I copied Leonardo da Vinci (left)?
