Earlier this week, two artists who work both on and off the street, Aakash Nihalani and Know Hope, teamed up for an unlikely yet spectacular collaboration. Nihalani, who's known for his 3D-looking works that jump out of walls and streets, did a simple, two-part treatment on either side of a wall joined by concrete. Know Hope added the birds found in many of his pieces flying out of Nihalani's squares. Overall, it's the best of their worlds in one piece, which pops even more because of the blue wall they chose to paint it on. Let's hope this isn't the last time they decide to work together.
