New York City Mass Transit has a program called MTA Arts for Transit and Urban Design, which commissions artists through a competitive selection process to create original, site-specific permanent artwork for stations. This spring, there was also auditioning for a role of a subway performer. Link and more info here.
Grand Central Diary is a video created by London Squared Productions. It is currently part of the exhibition “On Time / Grand Central at 100” (curated and organized by MTA Arts for Transit and Urban Design). It is now on view through July 7 at the New York Transit Museum Gallery, which is located at the terminal. Grand Central Diary is a short film that shows the everyday routines at the station from a fun and quarky perspective of animated objects at the terminal and nearby.
