I can make cheap, small-scale facsimiles, fangzhipin, to demonstrate some quality of the original. I can make exact replicas, pixel-perfect fuzhipin, to learn how the originals and their creators work. Or I can create shanzhai, unsolicited redesigns, commenting and riffing on the work of others. All these copies have an important role to play in the process of design.<p>Whether you believe that it’s worthwhile or worthless to copy, whether you think that copies are a valuable part of the design community or a scourge, you are using software, hardware, websites and apps that all owe their existence to copying.<p>As long as there is design, there will be copying.
