Wind plays a crucial yet often overlooked role in shaping urban microclimates and the usability of public spaces. Despite its importance, there is limited research on how wind circulation affects comfort, particularly in dense urban areas. In informal settlements like Vanjaravas, Ahmedabad, densely packed structures create a ‘skimming flow’ (H/W ratio > 0.65), restricting ventilation and leading to stagnant air and discomfort. This issue isn’t unique to Vanjaravas; it is evident in informal settlements worldwide, where unplanned developments result in similar microclimatic challenges.

Enter the pinwheel—a playful, colourful, and apt solution to this problem. As it spins, the pinwheel redirects airflow through narrow streets, breaking up stagnant air and improving ventilation. Inspired by local culture, where pinwheels are a staple at festivals, markets and beaches, these inserts bring a sense of familiarity and joy to the streetscape. They’re not just practical; they’re eye-catching, interactive, and irresistible to kids and adults alike, turning plain streets into lively spaces full of movement and joy.

Light as a breeze and cheap to make, these pinwheels are crafted from recycled plastic, making them sustainable and easy on the wallet. They can be hung anywhere—on walls, poles, or lines—and anyone can make them with whatever’s on hand. It’s a DIY design that’s simple, adaptable, and perfect for community involvement.
