There's a lot of unassuming buildings on Crosby Street in SoHo, but I know this one in particular because a certain famous rock star lived there, and a training brother of mine works in carpentry and got hired for a job there, and one of his crew members accidentally fucked up this rock star's window treatment and had to race to fix it before the rock star returned.
Anyways, there's a nifty feature on the sidewalk in front of this building. You can't really appreciate it during the day, but at dawn, dusk and at night, you see these:
