The video consists of a series of clips. Each of them features a location on the MIT campus, and either an item or a set of thirteen light-and-dark squares. Each clip also features a camera movement—either left-to-right or downwards.
As it turns out, this is a criss-cross puzzle with video clues. The MIT building number indicates the row or column number in the grid, and the camera movement determines whether the clue is Across or Down. The clips that show thirteen squares indicate the light-and-dark pattern of the rows and columns that don’t have clues along them.
The video clues are provided in alphabetical order. The clips that show thirteen light-and-dark squares are mixed in, indicating where the filled-in letters would fall in the order.
Once the grid is filled in, the letters on the diagonal (indicated by the phrase “marks the spot” in the flavor text) will spell out the phrase AFTER SUNDOWN.
