Commissioned through a collaboration of the Children's Discovery Museum and the San Jose Office of Cultural Affairs, Portal is a public artwork by JD Beltran that reflects upon the deep past, the collapse of time, and how we visualize time through art. It was inspired by the discovery of Lupe, the juvenile Columbian Mammoth (named after the Guadalupe River,) who was the subject of a major exhibition at the Children’s Discovery Museum. Portal was featured as an evening projection, 35' wide by 25' high, for eighteen months on the twelve-story AT&T building at the intersection of Almaden Boulevard and East San Fernando Street in downtown San Jose. It also had a companion website that further explained the imagery in the film.
