his Illuminated Block Party will feature an interactive art installation by Pneuhaus, that invites visitors to power their own experience with bike-driven generators. As participants pedal, they collectively transform into a neon-colored grove of sculptural trees. These inflatable forms change color and contours continuously in time with the momentum of the bikers. Racing together, the field of plant-like pieces will inflate, deflate, illuminate, and darken.

JFK Street will radiate in an awe-inspiring and immersive installation by ILLUMINUS who will showcase a public art experience reflecting off the facades of our historic and iconic buildings.

This event is free and open to the public. All are welcome to join this family-friendly celebration. Our entertainment schedule is as follows:
