According to this YouTube description: "vernal igloo! living on the streets of nyc for a month, i sometimes slept outside. a perfect spot in tompkins (no 5/0), completely undisturbed & obscured by green, i slept here on & off for about a week. big enough for 1, 4ft x 3ft x 7ft, enough room to sit up even!"
4ft x 3ft x 7ft apartments nearby are going for what now these days, $1,750? (And is that Emile Hirsch in the video?)
