Museum Van Loon curator Tonko Grever and artist Jill Magid slept for one night in the museum's Master Bedroom. The museum curator, by a stipulation the Van Loon family made when converting the house to museum, must live in the house's servant quarters during his tenure. The photograph of Magid and the curator in the master bed replaced a painted portrait of a Van Loon couple who had once occupied the room.
In The Small Bedroom the artist replaced the room's portrait paintings of the Van Loon Family with photographs of the museum staff members—from the curator to the janitor, who are otherwise generally hidden from view. The staff wore robes Magid made for them from the same, leftover material that covers the room's interior.Nightfall was made from the museum's surveillance footage taken the night when the artist and curator slept in the Master Bedroom. The footage montages time-lapse images from four of the museum's rooms, including the Master Bedroom, where they were spending the night.
