If you found yourself on New York Avenue over the past few months, you might have done a double take after seeing these colorful ladies in action. They're the work of French artist Niki de Saint Phalle whose whimsical sculptures make the Stravinsky Fountain near Paris's Pompidou Centre so memorable. On a gray day (as many of them have been lately), these zaftig but nimble souls from Saint Phalle's "Nana" series certainly cheered the streetscape. If you want to see them for yourself, act quickly. The installation, part of the neighboring National Museum of Women in the Arts New York Avenue Sculpture Project, runs only through the end of October.
