T+79_yellow is a constructed Lego wall sculpture that emulates the TV images of the Challenger Space Shuttle’s explosion.

Claire Healy and Sean Cordeiro have traveled all over the world for their work, but one of their must-see stops on their first trip to Europe wasn’t an art gallery or a museum. It was Legoland in Denmark, home of the tiny toy building block. Cordeiro said their trip was a “pilgrimage.” Cordiero said that the time he spent in Legoland played tricks on his mind. After a while, “You can’t figure out what’s made out of Legos, and what isn’t,” he said.

Cordiero and Healy chose Legos to make sense of an event that played tricks on their minds since childhood: the explosion of the Challenger space shuttle. The tragedy killed all seven crew members, including teacher Christa McAuliffe.

“It was one of those memories where you think you remember,” said Cordiero, who was in grade school at the time, watching from several time zones away. “I couldn’t have been at school, but I remember being at school.” Inspired by McAuliffe, who was supposed to teach children from space, the artists decided to use Legos to depict the tragedy.
