A iPod shot of the Mac computer screen showing downloaded photos from our recent New York City trip. Part of one of the bursts I took looking across to the opposite platform while waiting for the A train. Converted to B&W and adjusted for contrast and exposure to try to get rid of the gunky, colored, computer screen pattern on the white (not at all successfully, I see now -- additional post-posting adjustment in PicMonkey has helped, but also further abstracted it). Don't stare too long or you'll get sucked in by the Hermann-grid-like optical illusion dark spots at the intersections.
