The Triforium is a six-story, 60-ton public sculpture on the corner of Temple and Main Streets in downtown that was supposed to be a symbol of L.A.'s future. Unfortunately, technical problems plagued the project from the beginning and made it the subject of much ridicule. Now a group of L.A. enthusiasts want to restore the piece and realize the project's ambitious vision. This episode discusses the history of the Triforium and includes an interview with Tom Carroll, the creator and host of the web series "Tom Explores Los Angeles," who is involved in the restoration effort.
