Keys’ Metropolis My new art work Keys Metropolis is a series of illustrations to visualise fictional metropolis made up of keys. Its theme is to show the hidden shape’s similarity between keys and buildings. At first glance, it just looks like a line art of a large city, but looking closer, you could realise all the buildings are keys. By scanning the QR code on the bottom right of the pages, it is able to enjoy seeing the metropolis of 360 degrees by VR.
