This intervention that we developed for the Intramurs Contest 2016, in collaboration with EMT and its EMTExperience project, was titled “Being a pedestrian, being a snake.” It is a shout of gratitude to the city that changes, supporting public transport and better pedestrian circulation. We express our particular vision of sustainable mobility with this snake that sheds its skin through tape art. This unique and mobile piece, depicted on bus 5 Interior, traveled along the usual route of the line for the two weeks following the Contest.
