More than twenty-five MIT-affiliated artists added their individual contributions throughout spring 2017, culminating in a single, connected mural in May 2017. New murals and animations are added each semester. In addition to their work at MIT, the Borderline team has created AR animations for work by Takashi Murakami at the Museum of Fine Arts, Boston, and traveled to São Paulo, Brazil in summer 2018 to meet with artists and designers and create a collaborative work at the FabLab in the Porto Seguro Cultural Center. In 2018, Borderline was runner-up in HUB Madness, a competition for creative projects at the intersection of art, science, and tech in Boston, hosted by HUBweek.
