Subway Spotlight: Spotted on the tracks

Last night I was standing on the downtown #1 platform at 42nd street station, when i look down on the tracks and see this:
A rubik's cube. I can safely venture to say, that it's one thing i have never seen on the subway tracks before.

Though most items of any value that end up on the tracks seem to end up there accidentally, I sort of get the feeling this one was thrown down there in frustration. Actually, it reeks of something i would probably do. Damn you Rubik's cube!
