In 13 November 2021, the day of the first session of E-Uroboros, 5 artists from Poland, Canada, Japan, Malaysia, Egypt started to collaborate at the same time and handled to make “square in square” by using global video feedback system. Each participant utilized their own camera and monitor, microphone and speaker to generate visual and sound to the next participants, however those information finally returned to originator after few minutes. Thus whole session showed control and out of control in a rivalry through telecommunication system which became much familiar for us under COVID19 situation.
