Head over to the High Line to check out the new gigantic mural, "Brandon Many Ribs," by French artist JR. You'll spot it up around 29th Street. Then walk up to 46th Street and Eighth Avenue where the Art Production Fund is hosting an installation by Kiki Smith called "Chorus." It's made up of stained-glass stars spread throughout an empty lot and Kiki says the piece is "a tribute to Josephine Baker."

On the Upper East Side, the Metropolitan Museum of Art (1000 Fifth Avenue @ 82nd Street) has a cool new temporary-architecture work by Tomas Saraceno called "Cloud City." The rooftop installation is composed of lots of interlocking geodesic pods that can can walk around in and get a great view of Central Park. Also, if you haven't already gone, Tom Sachs "Space Program: Mars" over at the Park Avenue Armory on Lexington and 67th Street is a must-see.

Over in Long Island City, PAPER's Monica LoCascio -- along with Daria Brit Shapiro -- curated a group show, "Cosmic Architecture," that's up at Artists Wanted Gallery (25-25 44th Drive, LIC, Queens). The show has works by Maya Hayuk, Matt Jones, Max Gleason and more and it's up until June 17. Unfortunatly, MoMa PS1 won't be starting their Saturday Warm Up series of parties until July 7, but you still have a chance to check out the works by Lara Favaretto, Max Brand, Rania Stephan and Francis Stark, all of which are up until the end of May.

Finally, head to the Museum of Sex (233 Fifth Avenue) for the interesting group show "F*ck Art." The museum invited 20 international street artists to show their existing work or to create new works on their third floor. You'll find several NSFW pieces by artists including AIKO, Mode 2, Rostarr, JMR and Miss Van.
