I worked on the sixty-first floor of the tower, a height from which the streets could not be seen, but we were all gathered at the window that day, looking out at the rainbow spectacle. A flock of sky anemones was migrating through the city, slowly floating from west to east, back towards their home vortex over the open ocean. The jet stream had tossed them further north than usual this year, paralyzing the city below. Their elastic bodies bounced and rolled against the windows as they wandered, leaving venomous smears behind.
