Tom Otterness sculptures are hidden all over this city, turning New York into a giant scavenger hunt for these whimsical bronzes. But, one of the favorite places for kids to enjoy Otterness' works is a massive installation in Battery Park City officially called The Real World, but known by many parents as Penny Park. Kids love trying to figure out the meaning or story being told through the various sections of the park, and following the trail of pennies, but it's also just lots of fun to climb on and in the summer there's a water feature.

The 5 Pointz Aerosol Art Center is an outdoor art exhibit space in Long Island City where curator, Jonathan Cohen, is converting the exterior walls of a 200,000 sq ft factory building into a world renown graffiti art museum. You can see 5 Pointz from the elevated train or visit it at street level at Jackson Avenue and Davis Street in Queens. Sadly all of the graffiti at 5 Pointz was covered over in November 2013 and the building is slated for demolition.

If your child is interested in graffiti and other street art, then a virtual art outing on Streetsy might be an interesting diversion. Streetsy is a collaborative website where people from all over the world upload great graffiti and other works of street art. The site also has a NYC street art map that you can use to create your own cool street art walks.

And Don't forget about all the great art to discover in the subways. This website has a gallery of all the subway art. Check it out online, then take an art journey by rail.
