The problem with the coronavirus is that it is colourless and transparent. While riding a city bus in Berlin when the coronavirus started, I vaguely used to think that I wished it had colour and shape. Looking back, the things that have caused problems in history have always been colourless and transparent, lurking in our lives. I embroidered images of colourless and transparent things hidden in our daily lives that seem to have no problems and of them scattering.
