something i bet you didn't know

imagine that you're underground at the times square/42st subway stop.
can you picture how the A/C/E trains are set off aways from the rest - the 7, 1/9, N/R?
now, can you imagine that long tunnel/corridor that you walk through to get across town underground from the A/C/E to those other trains? this is the corridor with those signs hidden up in the metal rafters that say things like "overslept," "so tired," "why bother" with a picture of a rumpled bed at the end of the sequence.
okay. so imagine that corridor.
the lights in that corridor, in conjunction with the aforementioned metal rafters, cast a pattern on the white tiled walls that makes them look like argyle.
and this is the sort of thing that's hard to notice when the corridor is filled with people, but when it's empty or near-empty . . . argyle lighting all the way through.
