A book-lending kiosk for the Rose Fitzgerald Kennedy Greenway. Street furniture that doubles as a playground slide. A giant vibraphone on Fort Point Channel. And a 55-by-41-foot mural to transform the ceiling of City Hall into a bright blue sky.
These are among the winning ideas from the first Public Space Invitational in Boston, a contest for engineers, designers, architects, and other creative minds to enliven public spaces around the city.
