Observe sunspots by going to Grand Central Terminal?
The southern wall of the Grand Concourse, facing 42nd Street, has semicircular grills high up, with small curlicued spaces like those in a leafy tree. Many of those spaces act like the aperture of a pinhole camera, reflecting an image of the sun that, when it reaches the floor, will be 8 to 12 inches wide. The smaller grill spaces will produce dimmer but sharper solar images on your paper.

Let's say you're interested in movies and New York City. Then you could do worse than check out the Celluloid Skyline exhibit being displayed in Vanderbilt Hall in Grand Central from May 25 through June 22. The exhibit is based on the book of the same name by James Sanders, an exploration of how New York is portrayed in film. The exhibit includes "scenic backing" paintings made for movie sets in the 40s & 50s, film footage of films set in NYC, production stills and location shots, and other artifacts of NYC's intersection with film. Sanders was kind enough to send me a photo of one of the scenic backing paintings:
I left the tool chest in the foreground for scale...the paintings are three stories tall! I'm always down for a trip up to Grand Central so I'll definitely be checking this out.
