In downtown Boston, you might spot large pink inflatable sculptures called "Monsieur Rose" or "Mr. Pink." These are created by Parisian artist Philippe Katerine, known for his "cute-ism" or "Mignonisme" movement, as stated by CBS News Boston.

According to CBS News Boston, the Winteractive art walk in Boston adds colorful inflatable characters to the streets, brightening the city's cold winter months. According to the exhibit’s website, "These characters transform the streets into playful places and our daily travels into delightful, colorful journeys." New pieces will be added daily, including a quirky installation of a 1962 Canadian satellite crashed on a car hood, bringing unexpected fun and vibrancy to the city.

Winteractive, running through March 30, features 15 creative installations like "Living Lantern," "Sonic Runway," and "Celestial Garden." Starting January 15, the event transforms downtown Boston with interactive art that engages sight, sound, and touch. One standout is Monsieur Rose's oversized sculptures, which add a fun, whimsical touch to the winter scene, inviting people to explore and enjoy the city in new ways, as reported by WCVB.
